Incazelo Yomkhiqizo:
I-Malononitril iqinile engenambala (<25°C) enephuzu elibilayo elingu-220°C kanye nephoyinti elikhanyayo elingu-112°C. Amandla adonsela phansi aqondile ngu-D434.2:1.0488. Iyancibilika emanzini, incibilika kuzincibilikisi zemvelo ezifana ne-benzene notshwala, ayincibiliki emanzini abandayo, i-carbon tetrachloride, i-petroleum ether nexylene. I-Malononitrile ine-cyano- kanye ne-methylene eyodwa esebenzayo, enomsebenzi wamakhemikhali onamandla, ama-athomu ekhabhoni kanye ne-nitrogen angakwazi ukwenza ukusabela kokwengeza; ingakwazi ukwenza i-polymerize. Inobuthi, idala ukuphazamiseka kwe-neurocentric, iyagqwala futhi iyaqhuma.
Isicelo:
(1) I-Malononitrile iwumkhiqizo wokusetshenziswa wokulungiswa kwe-2-amino-4,6-dimethoxypyrimidine kanye ne-2-chloro-4,6-dimethoxypyrimidine, engasetshenziswa ukukhiqiza ama-sulfonylurea herbicides afana ne-bensulfuron ne-pyrimethamiphosulfuron, njll. Iphinde isetshenziselwe ukwenza i-herbicide i-diflubenzuron, esetshenziswa ekwenzeni imishanguzo ye-diuretic kwezokwelapha.
(2) I-Organic synthesis izinto zokusetshenziswa. Kwezokwelapha, isetshenziselwa ukuhlanganiswa kwe-vitamin B1, i-aminopterin, i-aminobenzyl pteridine kanye nochungechunge lwezinye izidakamizwa ezibalulekile. Inokusetshenziswa okubalulekile kodayi, izibulala-zinambuzane nezinye izinhlelo zokusebenza. Ingasetshenziswa futhi njengendlela yokukhipha igolide. Manje isetshenziswa e-China ikakhulukazi ukukhiqizwa kwe-aminopterin, i-bensulfuron, i-1,4,5,8-naphthalenetetracarboxylic acid kanye nemikhiqizo yochungechunge lwe-pyrimidine.
(3) Isetshenziswa emithini yemithi, iyindawo emaphakathi yesidakamizwa i-aminopterin.
(4) Ingasetshenziswa njengezinto zokusetshenziswa ze-organic synthesis, i-pharmaceutical intermediate kanye nezincibilikisi zemvelo.
