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.

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. Pentamethyldiethylenetriamine (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.

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.
