Antifungal properties of esters of alkenoic and alkynoic acids

Antifungal properties of esters of alkenoic and alkynoic acids. Huhtanen, C.Some chemicals with cas registry numbers like 624-49-7 and 1515-80-6 are also used. N.; Guy, E. J. (East. Reg. Res. Cent., ARS, Philadelphia, PA 19118, USA). J. Food Sci., 49(1), 281, 283 (English) 1984. CODEN: JFDSAZ. ISSN: 0022-1147. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The antifungal properties of the gas phases of a no. of alkenoic and alkynoic acids and esters was investigated by placing the compds. in desiccators contg. suspended bread. The following compds. inhibited mold development at 20 mg/2.6-L desiccator: dimethyl fumarate [624-49-7], diethyl fumarate [623-91-6], propenoic acid [79-10-7], methyl [96-33-3], and ethyl propenoate [140-88-5], methyl [922-67-8] and ethyl propiolate [623-47-2], methyl-2,4-hexadienoate [1515-80-6], 2,4-hexadien-1-ol [111-28-4], diethylethylidene malonate [1462-12-0], 4-penten-1-ol [821-09-0], and 2-cyclohexen-1-one [930-68-7]. Other compds. were active at 200 mg/desiccator: 3-methallyl alc. [513-42-8], allyl acetone [109-49-9], diallyl ether [557-40-4], propiolic acid [471-25-0], methyl [18707-60-3], ethyl [10544-63-5], and vinyl crotonate [14861-06-4]; ethyl-2,4-hexadienoate [2396-84-1]; methyl [2396-77-2] and ethyl 2-hexenoate [1552-67-6]; ethyl 3-hexenoate [2396-83-0]; 1,5-hexadien-3-ol [924-41-4]; methylmaleic acid [498-23-7]; methylmalonic acid [516-05-2]; and 1-penten-3-ol [616-25-1]. .

Electroinitiated polymerization of some acetylenic derivatives, a polarographic study

Electroinitiated polymerization of some acetylenic derivatives, a polarographic study. Simionescu, C. I.; Grovu, M.; Duca, A. (Dep. Macromol. Chem., Polytech. Inst., Iasi 6600, Rom.). Angew. Makromol. Chem., 115, 47-59 (English) 1983. CODEN: ANMCBO. ISSN: 0003-3146. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 72 The polarog. redn. of phenylacetylene [536-74-3], diphenyldiacetylene [886-66-8], and Me propiolate [922-67-8] and of some quaternary salts (ammonium, phosphonium, arsonium, and stibonium) was investigated.Several substances with their cas registry numbers 3084-10-4 and 27342-21-8 may be metioned in this study. The half-wave potential, the potential at the starting point of the redn., and the no. of electrons transferred in the electrode process were detd. to obtain information on the reversibility of the process. The redn. of acetylenic derivs. in the presence of quaternary ammonium salts was prevailed by the diffusion current. The impurities obsd. by the polarog. technique in base solns. were reducible and disappeared if the electrolyte soln. was previously reduced. Some quant. data on the polymn. kinetics were presented. .
