摘要: The present invention relates to a new process for the partial carbodiimidization of the isocyanate groups of organic mono-, or di- and/or polyisocyanates, the mixtures which can be obtained by this process and the use of these mixtures as isocyanate components in the production of polyurethane plastics by the known isocyanate polyaddition process. In general, the process comprises:

摘要: NEW MATERIAL:A compound shown by the formula I (R
1 , R
2 , and R
3 are H or lower alkyl; R
4 is chain or cyclic lower alkyl, phenyl, chain or cyclic lower alkylamino).
EXAMPLE: 5-(p-Normal-butyryl oxyphenyl)-1,3-dimethylbiuret.

摘要: NEW MATERIAL:A compound expressed by formulaI(R1 is phenyl or phenyl having a lower alkyl or lower alkoxyl as a substituent group; R2 and R3 are lower alkyl). EXAMPLE:2,5-Dimethyl-1-phenyl-2-isobiuret. USE:A medicine having anti-inflammatory, analgesic, antiallergic, diuretic, antimicrobial and anticonvulsant actions. PROCESS:An isourea expressed by formula II is reacted with an isocyanate expressed by formula III in a solvent, e.g. ether, benzene or chloroform, at a temperature in the range of -20 deg.C to the boiling point of the solvent to be used to give the compound expressed by formulaI. The reaction may be carried out under solventless conditions, and the ratio of the isourea to the isocyanate is preferably about 1:1.
