Product Description:
Malononitril yog cov khoom tsis muaj xim (<25 ° C) nrog qhov kub ntawm 220 ° C thiab lub teeb nyem ntawm 112 ° C. Nws lub ntiajteb txawj nqus yog D434.2: 1.0488. Nws yog soluble hauv dej, soluble hauv cov kuab tshuaj organic xws li benzene thiab cawv, insoluble hauv dej txias, carbon tetrachloride, roj av ether thiab xylene. Malononitrile muaj ob lub cyano- thiab ib qho reactive methylene, nrog rau cov tshuaj lom neeg muaj zog, ob qho tib si carbon thiab nitrogen atoms tuaj yeem nqa tawm cov tshuaj tiv thaiv ntxiv; tuaj yeem polymerize. Nws yog tshuaj lom, ua rau neurocentric mob, yog corrosive thiab tawg.
Daim ntawv thov:
(1) Malononitrile yog cov khoom siv raw rau kev npaj ntawm 2-amino-4,6-dimethoxypyrimidine thiab 2-chloro-4,6-dimethoxypyrimidine, uas tuaj yeem siv los tsim sulfonylurea tshuaj tua kab xws li bensulfuron thiab pyrimethamiphosulfuron, thiab lwm yam. kuj tseem siv los tsim cov tshuaj herbicide diflubenzuron, uas yog siv los tsim cov tshuaj diuretic hauv tshuaj.
(2) Organic synthesis raw khoom. Nyob rau hauv cov tshuaj, nws yog siv rau synthesis ntawm vitamin B1, aminopterin, aminobenzyl pteridine thiab ib tug series ntawm lwm yam tseem ceeb tshuaj. Nws muaj kev siv tseem ceeb hauv dyestuffs, tshuaj tua kab thiab lwm yam kev siv. Nws kuj tseem siv tau los ua cov extractant rau kub. Nws yog tam sim no siv nyob rau hauv Tuam Tshoj tsuas yog rau zus tau tej cov aminopterin, bensulfuron, 1,4,5,8-naphthalenetetracarboxylic acid thiab pyrimidine series khoom.
(3) Siv nyob rau hauv pharmaceuticals, nws yog ib qho nruab nrab ntawm cov tshuaj aminopterin.
(4) Nws tuaj yeem siv los ua cov khoom siv raw rau cov organic synthesis, tshuaj intermediates thiab cov kuab tshuaj organic.
