Chemical composition of the vapor-gas mixture evolved during wood delignification by aqueous solutions of acetone and ammonia. Draganova, R.; Kumanova, B.; Tsaneva, D.; Aleksiev, B.; Khristov, Ts. (Khim.-Tekhnol. Inst., Sofia 1156, Bulg.). Cellul. Chem. Technol., 18(3), 309-12 (Russian) 1984. CODEN: CECTAH. ISSN: 0576-9787. DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 80 The main components of the gas-vapor mixt. isolated during the delignification of wood with aq. Me2CO (I) [67-64-1] and NH3 were: MeOH [67-56-1], I, AcOH [64-19-7], 1,1,2,2-tetramethylpropane [464-06-2], 2,4,6-trimethylpyridine [108-75-8], bicyclo[3.3.0]octane [694-72-4], and allyl 3-oxobutanoate [1118-84-9]. The concn. of the components was detd. by gas chromatog. and mass spectrometry.

Kokai Tokkyo Koho JP 61193882 A2 28 Aug 1986 Showa, 7 pp. 1118-84-9 and 79-10-7 are cas registry numbers. These chemicals are also mentioned in this article. (Japan) CODEN: JKXXAF. CLASS: ICM: B41M005-18. ICS: C08F261-04; D21H001-40; G03C011-08. ICA: B32B027-10. APPLICATION: JP 85-32816 22 Feb 1985. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 42, 43 The claimed coating compns. contain an aq. soln. of a graft copolymer of poly(vinyl alc.) (or its modified copolymer), (meth)acrylamide, and 31 acetoacetyl group-contg. monomer. The compns. may also contain a crosslinking agent having functional groups which react with acetoacetyl groups. The coating compns. are esp. useful for thermal recording paper and photog. paper. .
