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.
