NT CAT PC-8 CAS No.:98-94-2 Synthesis method and application

NT CAT PC-8 CAS No.:98-94-2 Synthesis method and application Brief introduction. Chemical Chinese name: N,N-dimethylcyclohexylamine Chemical English name: N,N-dimethylcyclohexylamine; dimethyl aminocy clohexane Chemical Alias: Dimethyl aminocyclohexane CAS No.: 98-94-2 EC No.: 202-715-5 Molecular formula: C8H17N Synthesis method. N,N-dimethylaniline catalytic chlorination method In 1904, Sabatier et al. carried out the gas-phase hydrogenation of N,N a dimethylamine at a temperature of 160-180°C and at atmospheric pressure to produce DMCHA. Phenol method This method uses Pd or Rh as the catalyst, and phenol dimethylamine and hydrogen as raw materials. For example, when Pd is the catalyst, the catalyst dosage is 0.2~0.5, and the process conditions are 60~150℃, hydrogen pressure 0.15~0.48MPa, reaction time 6h, and the yield is between 70~80%. The raw material is available, and the reaction conditions are mild, but the catalyst is made of precious metals, and the yield is low. Cyclohexylamine method The process also uses formaldehyde and formic acid to react with cyclohexylamine, or uses oxides of Bi, Sb, Mg, A1, Lu, etc. as catalysts to react cyclohexylamine with methanol to methylate cyclohexylamine to produce DMCHA. the disadvantage of this method is the low selectivity of the former reaction, and the yield of the later methylation is not high. Cyclohexanone method Among the methods for the synthesis of DMCHA, the reductive amination method using cyclohexanone as raw material has more advantages: high conversion, yield and selectivity. The processes using Pd/C catalyst or Cu-A1 catalyst have their own characteristics and are currently under development in China. Uses. [Use I] Mainly used as polyurethane hard foam catalyst [Use II] N,N-dimethylcyclohexylamine can be used in a wide range of rigid foams. N,N-Dimethylcyclohexylamine is also suitable for the manufacture of rigid foam furniture frames and decorative parts. It can be used as the main catalyst alone in rigid foam products without the addition of organotin, or it can be supplemented with JD series catalysts according to the process and product requirements. It is also used as intermediate of rubber accelerator and synthetic fiber. Use III】It is used as intermediate of dyestuff, used to make vanillin, azo dyestuff, triphenylmethane dyestuff, also can be used as solvent, stabilizer, analysis reagent, etc.. Also used as catalyst. Storage and transportation. Should be sealed and stored in a dry, cool and ventilated warehouse Package: 200KG/drum 200KG/drum Storage: It is recommended to store in dry and cool area with proper ventilation. Please fasten the lid as soon as possible after original packaging to prevent the mixing of other substances such as moisture and other substances from affecting the product performance.

NT CAT PC-5 CAS No.: 3030-47-5 Product Application

NT CAT PC-5 CAS No.: 3030-47-5 Product Application Brief introduction. Chemical name: N,N,N′,N′,N″-Pentamethyldiethylenetriamine Alias: Pentamethyldiethylenetriamine Abbreviation: PMDETA English name: N,N,N′,N′,N″-pentamethyldiethylenetriamine Molecular formula: C9H23N3 Relative molecular mass 173.3 CAS No. 3030-47-5 Applications. Pentamethyldieth , ylenetriamine (PMDETA) is a highly active tertiary amine foaming catalyst, PMDETA has a strong foaming effect, which can improve the flow of foam and enhance the quality of products.PMDETA can also be used as a ligand for polyurethane foam catalysts and a ligand for functional polymerization materials. In addition, other applications are exemplified as follows. 1. Preparation of a two-phase amine absorber for capturing CO2. The two-phase amine absorber is a three-component system consisting of diethylenetriamine, pentamethylenetriamine, and water, and the total concentration of diethylenetriamine and pentamethylenetriamine in water is 4~5 mol/L, and the molar ratio of diethylenetriamine to pentamethylenetriamine is 1:4~4:1; these two organic amines alone do not have the ability to split the phase after absorbing CO2 in aqueous solution, but the two-phase amine absorber composed of the three-phase system But the two-phase amine absorber composed of this ternary system has the performance of phase separation, which is a homogeneous solution before absorbing CO2, and is divided into two phases after absorbing CO2 saturation. After saturated absorption, CO2 is enriched in the aqueous phase, and after phase separation, only the solution enriched in the CO2 phase needs to be regenerated thermally, thus greatly reducing the amount of enriched liquid required for regeneration, effectively reducing regeneration energy consumption, and also maintaining efficient CO2 absorption performance, which has a wide range of application prospects. 2. A methanol gasoline power accelerator. The accelerator consists of: isooctanol, aminoacetaldehyde diethyl acetal, 1,5- cyclooctadiene, 2-acetylbenzofuran, propargyl alcohol, n-propanol, zinc naphthenate, dinonyl naphthalene sulfonic acid, dipolyoxyvinyl aliphatic amine, and pentamethyldiethylenetriamine. The preparation method includes: a. Add isooctanol, aminoacetaldehyde diethyl acetal, 1,5-cyclooctadiene, 2- acetylbenzofuran to the reaction kettle and stir the reaction for 40-50 minutes at 60-62°C with closed ultrasonic stirring, b. Mix n-propanol, zinc naphthenate, dinonyl naphthalenesulfonic acid and stir for 15-25 minutes; c. Add propargyl alcohol, the mixture in step b, dipolyoxyvinyl fatty amine, pentamethyl diethylenetriamine, add them to the mixture in step a in turn, stir for 20~25 minutes at 33~35℃, and then cool down to obtain. Quality index. Content: ≥98% Specific gravity: 0.8330-0.8410 Refractive index: 1.4430-1.4450 Storage and transportation.

CAS: 90-72-2 2,4,6-Tris(dimethylaminomethyl)phenol Production Process and Method Brief introduction. 2,4,6-tris(dimethylaminomethyl)ph , enol, an organic chemical substance, molecular formula: C15H27N3O. Chinese name: 2,4,6-tris(dimethylaminomethyl)phenol Foreign name: 2,4,6-Tris(dimethylaminomethyl)phenol English alias: 2,4,6-tris[(dimethylamino)methyl]phenol Alias: Epoxy accelerator DMP-30; Tris(dimethylaminomethyl)phenol Appearance: transparent liquid Chemical formula: C15H27N3O Molecular weight: 271.4314 CAS No.: 90-72-2 EINECS number: 202-013-9 Boiling point: 320.50 ℃ Density: 1.054 g/cm³ Flash point: 116.63 ℃ Refractive index: 1.517 Epoxy resin curing accelerator DMP-30 is 2,4,6 tris(dimethylaminomethyl)phenol, which is a tertiary amine curing agent. It can be used as an epoxy resin curing agent at room temperature, and also as an efficient accelerator for acid anhydride, polyvinylamine and aliphatic polyamine curing agents. This product contains phenolic hydroxyl group in its molecular structure, so the activity is increased and it can be used for fast curing, mainly for thermosetting epoxy resin curing agent and adhesive, and it can be used as accelerator of acid anhydride curing agent and amide curing agent for casting and pressure layer products, the amount of this product as curing agent is generally about 3-13%, and the amount as accelerator is generally 0.1-3%. This product can be used as a catalyst in rubber anti-ozone agent and rigid polyurethane foam raw material combination polyether. Production process. 2000L reaction kettle, 200kg of phenol, 720kg of dimethylamine, 520kg of formaldehyde added dropwise below 50 degrees. kg, after drop addition, raise the temperature to 70 degrees, keep warm for 2 hours, lower the temperature to 50 degrees, add 100 kg of sodium chloride Sodium chloride, stir, let stand, stratify, and dehydrate the crude product under pressure. Method of preparation. After the reaction of phenol with dimethylamine and formaldehyde, the reaction products are stratified, dehydrated under vacuum and filtered to obtain the finished product. Theoretical unit consumption: (one ton of product) Phenol: 400 kg Dimethylamine (40% aqueous solution) 1440kg Formaldehyde (37% aqueous solution) 1040kg Produce waste water about 1.8 tons, mainly containing a small amount of formaldehyde Dosage: As accelerator dosage is about 1~5% As a curing agent dosage of about 10% Application areas. Use one Used as curing agent for thermosetting epoxy resin, adhesive, binder for laminate material and flooring, acid neutralizer and catalyst in polyurethane production Application 2 Used as antioxidant, also used in dye preparation Application 3 Used as curing agent for thermosetting epoxy resin, adhesive, sealant for laminate materials and flooring, acid neutralizer and catalyst in polyurethane production.
