Hōʻike huahana:
He paʻa kala ʻole ʻo Malononitril (<25°C) me ka helu hoʻolapalapa o 220°C a me kahi kiko uila o 112°C. ʻO D434.2:1.0488 kona ʻumekaumaha kikoʻī. Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia e like me benzene a me ka waiʻona, hiki ʻole ke hoʻoheheʻe ʻia i ka wai anuanu, carbon tetrachloride, petroleum ether a me xylene. Loaʻa iā Malononitrile ʻelua cyano- a me hoʻokahi methylene reactive, me ka hana kemika ikaika, hiki i nā ʻātoma kalapona a me ka nitrogen ke hana i nā hopena hoʻohui; hiki ke polymerize. He mea ʻawaʻawa, hoʻoulu i nā maʻi neurocentric, ʻino a pahū.
Noi:
(1) Malononitrile ka mea maka no ka hoʻomākaukauʻana i ka 2-amino-4,6-dimethoxypyrimidine a me ka 2-chloro-4,6-dimethoxypyrimidine, hiki ke hoʻohanaʻia e hana i nā sulfonylurea herbicides e like me bensulfuron a me pyrimethamiphosulfuron, etc. hoʻohana ʻia e hana i ka herbicide diflubenzuron, i hoʻohana ʻia i ka hana ʻana i nā lāʻau diuretic i ka lāʻau lapaʻau.
(2) Hoʻohui ʻia i nā mea maka. I ka lāʻau lapaʻau, hoʻohana ʻia ia no ka synthesis o ka vitamin B1, aminopterin, aminobenzyl pteridine a me nā ʻano lāʻau nui ʻē aʻe. He hoʻohana koʻikoʻi ia i nā mea pena, nā pesticides a me nā noi ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he extractant no ke gula. Hoʻohana nui ʻia ia ma Kina no ka hana ʻana o aminopterin, bensulfuron, 1,4,5,8-naphthalenetetracarboxylic acid a me nā huahana pyrimidine series.
(3) Hoʻohana ʻia i nā lāʻau lapaʻau, he mea waena ia o ka aminopterin lāʻau lapaʻau.
(4) Hiki ke hoʻohana ʻia e like me nā mea maka no ka synthesis organik, nā mea waena lāʻau lapaʻau a me nā solvents organik.
Pūʻolo:25 kgs / ʻeke a i ʻole e like me kāu noi.
Waihona:E kūʻai ma kahi ea, maloʻo.
