GB 2122491 A1 18 Jan 1984, 9 pp. (English). (United Kingdom). CODEN: BAXXDU. CLASS: IC: A61K007-22. APPLICATION: GB 83-17561 28 Jun 1983. PRIORITY: JP 82-114505 30 Jun 1982. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 63 Aq. dentifrices and mouthwashes contg. amino compds. may discolor by way of reaction with aldehydes present in flavorings. An unsatd. cyclic aldehyde free of phenolic OH groups and with the CHO group attached to 1 of the C atoms of the double bond, a C4-7 or C9-16 aliph. aldehyde with no double bond a or b to the CHO group, and an aliph. aldehyde with a double bond between the a and b C atoms and a C1-12 alkyl or aralkyl group attached a to the CHO group and a total C no. of 5-16 are compatible with the amino compds. The amino compd. may be a plasmin [9001-90-5] inhibitor. A mouthwash contg. tranexamic acid [1197-18-8] 0.2, carvone 0.2, l-menthol 0.2, aldehyde flavor 0.2, EtOH 12.0, polyoxyethylene hydrogenated castor oil 4.5, glycerin 10.0, Na saccharin 0.5, and H2O to 100% was discolored when held at 50° for 2 days if the aldehyde was acetaldehyde, cinnamaldehyde, or propanal, but was not if it was such compds. as 3-methylbutanal [590-86-3], citronellal [106-23-0], anisaldehyde [123-11-5], or a-methylcinnamaldehyde [101-39-3]. .

Solvent effect on the peroxide epoxidation rate of a,b-unsaturated aldehydes

Solvent effect on the peroxide epoxidation rate of a,b-unsaturated aldehydes. Tishchenko, I. G.In this study， 101-39-3 and 104-55-2 are also used.; Burd, V. N.; Revinskii, I. F. (Beloruss. Gos. Univ., Minsk, USSR). Dokl. Akad. Nauk BSSR, 30(9), 826-8 (Russian) 1986. CODEN: DBLRAC. ISSN: 0002-354X. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The rate const. (k) for epoxidn. of cinnamaldehyde by H2O2 in aq. MeOH increased with increasing MeOH content. Also, k for 80% aq. org. solvents increased in the following order of org. solvent: dioxane < MeCN < MeOH < DMF < Me2SO. In the case of a-methylcinnamaldehyde, k in aq. dioxane mixts. decreased with increasing dioxane content. .
