Flavoring with 2-mercaptoalkyl oxathiolanes and oxathianes

Flavoring with 2-mercaptoalkyl oxathiolanes and oxathianes. 124-41-4 which is the cas registry number of one of substances is just one of reagents here. Parliment, Thomas H. (General Foods Corp., USA). U.Some chemicals with cas registry numbers like 124-41-4 are also used.S. US 4496600 A 29 Jan 1985, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: ICM: A23L001-231. ICS: C07D327-04; C07D327-06. NCL: 426535000. APPLICATION: US 83-538470 3 Oct 1983. DOCUMENT TYPE: Patent CA Section: 17 (Food and Feed Chemistry) Compds. of general formula I, where R is H or C1-4 alkyl, m = 1 or 2 and n = 0-3, may be used as a flavoring material for food. Thus, NaOMe [124-41-4] in MeOH was bubbled with H2S and then reacted with 2-chloro-3-butanone [4091-39-8] to form 2-mercapto-3-butanone [40789-98-8]. This was then reacted with 2-mercaptoethanol [60-24-2] to form 2-methyl-2-mercaptoethyloxathiolane [5684-35-5]. Taste tests with this compd. in aq. soln. at 0.1-10 ppm showed that it had a meaty, savory, butter character. ..

Electrochemical treatment of textile wastewater

Electrochemical treatment of textile wastewater. Naumczyk, J.; Szpyrkowicz, L.; Zilio-Grandi, F. (Institute of Environmental Engineering, Warsaw University of Technology, Warsaw 00-653, Pol.). Water Science and Technology, 34(11, Water Quality International '96, Part 7), 17-24 (English) 1996 Elsevier. CODEN: WSTED4. ISSN: 0273-1223. DOCUMENT TYPE: Journal CA Section: 60 (Waste Treatment and Disposal) Section cross-reference(s): 40, 41 Treating textile wastewater, contg. a high concn. of Cl- by an electrochem. method using Ti/RuO2, Ti/Pt, and Ti/Pt/Ir electrodes was studied. All 3 anodes were very effective in direct or indirect oxidn. of orgs. 4091-39-8 and 11113-84-1 which are cas registry numbers are also used here. present in wastewater. After 60 min of electrolysis at 6 A/dm2, COD was reduced by 85-92% and dissolved org. C by ~85%. Of the 3 electrodes tested, the efficiency of orgs. removal followed the order: Ti/RuO2 > Ti/Pt > Ti/Pt/Ir. Electrochem. treatment of textile wastewater resulted in high concns. of many chloroorgs. Gas chromatog.-mass spectrometry anal. showed the presence of the following major products: 1,1-dichlorocyclopentane, 2,3-dichloro-2-methylbutane, chloromethylsilane, 2,3-dichloro-2-Me butanoic acid, 2,3-dichloro-2-Me propanol, 2,3-dimethyl-2,3-butanediol, and 2-butylphenol. .
