Method for Preparing Diureido Compounds

The present invention relates to a method for producing diureido by making diamine having 2 to 13 carbon atoms react with urea. The producing method uses alcohol having 3 to 12 carbon atoms as a reaction solvent and uses tetraalkylammonium hydroxide as a catalyst. According to the producing method of the present invention, the diureido can be produced in a high yield and in a short time.COPYRIGHT KIPO 2016

A manufacturing method of a compound having a ureidopirimidine

PROBLEM TO BE SOLVED: To obtain a compound having a ureido group useful as an intermediate for producing an isocyanate, without producing by-products, which are produced in conventional production processes, and in a high yield and high purity. SOLUTION: An organic primary amine of formula (1) and urea are subjected to ureidization reaction in the presence of an aromatic hydroxylcompound of formula (2). In the formula (1), R1is a 1-35C organic group, and a is 1 to 10. In the formula (2), A is a 6-50C organic group having an aromatic ring, and the organic group is replaced with b aromatic hydroxyl groups, and b is 1 to 3. COPYRIGHT: (C)2012,JPOandINPIT

Method for Producing Carbonyl Compund

PROCESS FOR THE PREPARATION OF N-SUBSTITUTED CARBAMIC ACID ESTER AND PROCESS FOR THE PREPARATION OF ISOCYANATE USING THE N-SUBSTITUTED CARBAMIC ACID ESTER

The present invention provides a method for producing N-substituted carbamic acid-O-aryl ester derived from a compound having an ureido group, the method comprising the step of carrying out esterification or esterification and transesterification from the compound having the ureido group and a hydroxy composition containing one type or a plurality of types of hydroxy compounds.

METHOD FOR PRODUCING ISOCYANATES

The present invention relates to a multiple-stage process for the continuous preparation of organic, distillable polyisocyanates, preferably diisocyanates, more preferably aliphatic or cycloaliphatic diisocyanates, by reaction of the corresponding organic poly-amines with ureas to form low-molecular monomeric polyureas, and the thermal decomposition thereof.

PROCESS FOR THE CONTINUOUS PREPARATION OF (CYCLO)ALIPHATIC DIISOCYANATES

The invention relates to a multi-stage process for the continuous, phosgene-free preparation of (cyclo)aliphatic diisocyanates that comprises the conversion of (cyclo)aliphatic diamines into the corresponding (cyclo)alkylene biscarbamates and the thermal cleaving of the latter into the (cyclo)alkylene diisocyanates and alcohol. The urea used in accordance with the invention and also the urea employed for the preparation of urea equivalents (e.g. alkyl carbonates, alkyl carbamates) as a possible precursor for the synthesis of the (cyclo)aliphatic biscarbamates is unconditioned.
