Tlhaloso ea Sehlahisoa:
Malononitril ke ntho e thata e senang 'mala (<25°C) e nang le ntlha e belang ea 220°C le flash point ea 112°C. Matla a eona a khoheli a khethehileng ke D434.2:1.0488. E qhibiliha ka metsing, e qhibiliha ka har'a metsoako ea tlhaho e kang benzene le joala, ha e qhibilihe metsing a batang, carbon tetrachloride, petroleum ether le xylene. Malononitrile e na le li-cyano tse peli le methylene e le 'ngoe e sebetsang ka matla, e nang le lik'hemik'hale tse matla, liathomo tsa carbon le naetrojene li ka etsa liphetoho tse eketsehileng; e ka etsa polymerize. E na le chefo, e baka mathata a neurocentric, e senya ebile ea phatloha.
Kopo:
(1) Malononitrile ke thepa e tala bakeng sa ho lokisetsa 2-amino-4,6-dimethoxypyrimidine le 2-chloro-4,6-dimethoxypyrimidine, e ka sebelisoang ho hlahisa likokoana-hloko tsa sulfonylurea tse kang bensulfuron le pyrimethamiphosulfuron, joalo-joalo. E boetse e sebelisoa ho etsa herbicide diflubenzuron, e sebelisoang ho etsa litlhare tsa diuretic meriana.
(2) Organic synthesis lisebelisoa tse tala. Meriana, e sebelisetsoa ho kopanya vithamine B1, aminopterin, aminobenzyl pteridine le letoto la lithethefatsi tse ling tsa bohlokoa. E na le ts'ebeliso ea bohlokoa ho dae, chefo e bolaeang likokoanyana le lits'ebetsong tse ling. E ka boela ea sebelisoa e le mokelikeli oa khauta. Hona joale e sebelisoa Chaena haholo-holo bakeng sa tlhahiso ea aminopterin, bensulfuron, 1,4,5,8-naphthalenetetracarboxylic acid le lihlahisoa tsa letoto la pyrimidine.
(3) E sebelisoa meriana, ke karolo e bohareng ea lithethefatsi tsa aminopterin.
(4) E ka sebelisoa e le lisebelisoa tse tala bakeng sa motsoako oa manyolo, li-intermediate tsa meriana le li-solvents tsa organic.
