ジイソシアナートと活性水素を有する化合物との付加化合物の合成とその反応

抄録

A series of addition-Compounds as an isocyanate generator was synthesized by reaction of tetramethylenediisocyanate or methylene di-(p-phenylene) diisocyanate with a active hydrogen compound. The active hydrogen compounds used here were phenol, m-cresol, diethyl malonate, ethyl acetoacetate, ethyl cganoacetate, α-pyrrolidone, ε-caprolactam, and sodium hydrogen sulfite.
As a qualitative test for easiness of thermal dissociation, diamine test was made and the same result was obtained as that of Cellit test as reported. by Petersen.
