Hōʻike huahana:
ʻO ka ʻakika malonic, ʻike ʻia hoʻi ʻo malonic acid, he ʻakika olaola me ke ʻano kemika HOOCCH2COOH, hiki ke hoʻoheheʻe ʻia i ka wai, nā ʻawaʻawa, nā eter, acetone a me ka pyridine, a aia ma ke ʻano he paʻakai calcium i nā aʻa beet sugar. ʻO ka ʻakika malonic he aniani ʻeleʻele kala ʻole, ka helu heheʻe 135.6°C, decomposes ma 140°C, density 1.619g/cm3 (16°C).
Noi:
(1) Hoʻohana nui ʻia e like me nā intermediates pharmaceutical, hoʻohana ʻia i nā mea ʻala, adhesives, resin additives, electroplating and polishing agents, etc.
(2) Hoʻohana ʻia ma ke ʻano he mea paʻakikī, hoʻohana pū ʻia i ka hoʻomākaukau ʻana i ka paʻakai barbiturate, etc.
(3) ʻO ka malonic acid kahi mea waena o ka fungicide raiki fungicide, a he mea waena hoʻi o ka mea hoʻoponopono ulu ulu indocyanate.
(4) Malonic acid a me kona mau esters ua hoʻohana nuiʻia i nā meaʻala, adhesives, resin additives, pharmaceutical intermediates, electroplating and polishing agents, explosion control agents, hot welding flux additives, etc. , barbiturates, vitamina B1, vitamina B2, vitamin B6, phenyl pausticum, amino acids, etc. Hoʻohana ʻia ka malonic acid ma ke ʻano he lāʻau lapaʻau ma luna o ka alumini a ʻaʻohe pilikia pollution no ka mea ʻo ka wai a me ke kalapona kalapona wale nō e hana ʻia ke hoʻomehana ʻia a decomposed. . Ma kēia ʻano, ʻoi aku ka maikaʻi ma mua o nā lāʻau lapaʻau e like me ka formic acid, i hoʻohana ʻia i ka wā ma mua.
(5) Hoʻohana ʻia ka malonic acid ma ke ʻano he mea hoʻohui no ka plating kemika a ma ke ʻano he polishing agent no ka electroplating.
Pūʻolo:25 kgs / ʻeke a i ʻole e like me kāu noi.
Waihona:E kūʻai ma kahi ea, maloʻo.
