DOCUMENT TYPE: Journal CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 80 The absorption coeff. spectra of CF2Cl2 [75-71-8] at 915-930/cm were recorded and optimal conditions for detn. of CF2Cl2 in air were detd. The min. detectable concn. was detd.

Corrosion inhibitors for aerosol products

Corrosion inhibitors for aerosol products. (Seitetsu Chemical Industry Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59126491 A2 21 Jul 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09K003-30; C23F011-12; C23F011-16. APPLICATION: JP 83-864 6 Jan 1983. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) Aerosol products showing corrosion are inhibited by adding 31 glycidyl compd. Corrosion by aerosol products (e.g., hair sprays, deodorants, and antiphlogistics) is decreased. Thus, EtOH 31, water 10, Plascize L-1260 2.5, and Epiol E-100 (ethyleneglycol glycidyl ether) [55126-81-3] 0.5 g were mixed, dissolved, and mixed with 28% aq. NH3 to adjust to pH 8. The soln. was then filled into a tin can with Freon 11 [75-69-4] 28 and Freon 12 [75-71-8] 28 g. After standing at 45° for 1 mo, no corrosion was obsd.
