SYNTHESIS OF N-(1-URACILYLALKYL)POLYMETHYLENEDIAMINES

The alkylation of polymethylenediamines with 2-(1-uracilyl)ethyl bromide and 3-(1-uracilyl)propyl bromide yields the corresponding N-(1-uracilylalkyl)polymethylendiamines.

Method for Preparing Dicarbamate Compounds

The present invention provides a preparing method of dicarbamate, comprising: a first step of obtaining an alcohol solution including diureido obtained by reacting diamine having 2 to 13 carbon atoms with urea in the presence of alcohol having 3 to 12 carbon atoms at low temperature of 150anddeg;C or less; and a second step of obtaining dicarbamate by reacting the alcohol solution including the diureido at high temperature of 200anddeg;C or more under carbon dioxide pressure. According to the preparing method of the present invention, yield and selectivity of dicarbamate are significantly increased, and formation of an alkylated amine by-product can be minimized.COPYRIGHT KIPO 2016
