FIXING AGENT IN LUBRICANTS FOR GLASS FIBER AND AROMATIC POLYESTERS AND METHOD FOR ITS PREPARING Russian patent published in 2007 - IPC C07C255/26 C07C253/30

Abstract RU 2301224 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to novel compounds of the formula: , that are used as a fixing agent in lubricants for glass fibers and aromatic polyesters. Also, invention relates to a method for synthesis of these compounds. Method involves interaction of ethylenediamine with acrylonitrile in the presence of a catalyst of the formula (C₂H₅)₄NO(C₂H₅) or (CH₃)₄NO(CH) taken in the amount 0.1-0.3 wt.-% to amine. Reaction is carried out at temperature 30-40°C followed by treatment of synthesized compound with formaldehyde and then with acetic acid at temperature 30-40°C wherein the ratio ethylenediamne : acrylonitrile : formaldehyde : acetic acid = 1:2:2:2, respectively.

EFFECT: improved method of synthesis.
