Ingcaciso yeMveliso:
I-Malononitril yinto eqinileyo engenambala (<25°C) eneqondo lokubila elingu-220°C kunye ne-flash point ye-112°C. Ubunzima bayo obuthile ngu-D434.2:1.0488. Iyanyibilika emanzini, inyibilika kwizinyibilikisi zendalo ezifana nebenzene kunye ne-alcohol, ayinyibiliki emanzini abandayo, i-carbon tetrachloride, i-petroleum ether kunye nexylene. I-Malononitrile ine-cyano- kunye ne-methylene enye esebenzayo, kunye nomsebenzi oqinileyo weekhemikhali, zombini ii-athomu zekhabhoni kunye ne-nitrogen zingenza ukusabela okongeziweyo; ingenza i-polymerize. Iyityhefu, ibangela ukuphazamiseka kwe-neurocentric, i-corrosion kwaye iyaqhuma.
Isicelo:
(1) I-Malononitrile yinto eluhlaza yokulungiswa kwe-2-amino-4,6-dimethoxypyrimidine kunye ne-2-chloro-4,6-dimethoxypyrimidine, engasetyenziselwa ukuvelisa i-sulfonylurea herbicides ezifana ne-bensulfuron kunye ne-pyrimethamiphosulfuron, njl njl. Ikwasetyenziselwa ukwenza i-herbicide i-diflubenzuron, esetyenziswa ekwenzeni amayeza omchamo kwiyeza.
(2) Organic synthesis imathiriyeli ekrwada. Kwiyeza, isetyenziselwa ukuhlanganiswa kwe-vitamin B1, i-aminopterin, i-aminobenzyl pteridine kunye nochungechunge lwezinye iziyobisi ezibalulekileyo. Inokusetyenziswa okubalulekileyo kwidayi, izitshabalalisi kunye nezinye izicelo. Isenokusetyenziswa njengento yokutsalwa kwegolide. Ngoku isetyenziswa e-China ikakhulu ukuveliswa kwe-aminopterin, i-bensulfuron, i-1,4,5,8-naphthalenetetracarboxylic acid kunye neemveliso ze-pyrimidine series.
(3) Isetyenziswe kumachiza, yinto ephakathi kwi-aminopterin yeziyobisi.
(4) Ingasetyenziswa njengezinto eziluhlaza kwi-organic synthesis, i-pharmaceutical intermediates kunye ne-organic solvents.
