Stabilization of quaternary ammonium salts of dialkylaminoalkyl (meth)acrylates: Stabilization of quaternary ammonium salts of dialkylaminoalkyl (meth)acrylates. Nishikaji, Takashi; Watanabe, Kenzo; Sawayama, Shigeru (Mitsubishi Chemical Industries Co., Ltd., Japan). Japan. Kokai JP 51127016 5 Nov 1976 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C093-233. APPLICATION: JP 75-50488 25 Apr 1975. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Aq. solns. of the title ammonium salts were stabilized by adding 50-1000 ppm polymn. inhibitor and .gtoreq.1.8 ppm O. Thus, to an aq. 6891-44-7 and 95-71-6 which are cas registry numbers are also used here. soln. of 80% CH2:CHMeCO2(CH2)2N+Me3 X- (I, X = Cl) was added 100 ppm 2-methylhydroquinone and 2.2 ppm O was bubbled into it. The soln. was kept 7 days at 50.degree. without polymn., whereas a similar soln. contg. 0.4 ppm O, polymd. in 3 h. An aq. soln. of I (X = MeSO4) was similarly stabilized. .
