ʻIke ʻia ka Dimethyl carbonate ma ke ʻano he wai moakaka, ʻaʻohe kala me kahi ʻala ʻoluʻolu. ʻOi aku ka paʻa ma mua o ka wai a hoʻoheheʻe iki ʻia i ka wai. ʻOi aku ke kaumaha o nā mahu ma mua o ka ea. Hoʻohana ʻia e hana i nā kemika ʻē aʻe a ma ke ʻano he mea hoʻoheheʻe no ke kumu kūikawā.

Hoʻohana
Hoʻohana ʻia ka Dimethyl carbonate ma ke ʻano he mea hoʻoheheʻe i ka synthesis organik a ua manaʻo ʻia he pani no ka mea hoʻoheheʻe e like me ka methyl ethyl ketone, tert-butyl acetate a me ka parachlorobenzotrifluoride. Pili ia ma ke ʻano he waena i ka hoʻomākaukau ʻana o ka diphenylcarbonate, kahi i hoʻohana ʻia ma ke ʻano he mea maka nui no ka synthesis o Bisphenol-A-polycarbonate. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea methylating 'ʻōmaʻomaʻo' e pili ana i ka methylation o aniline, phenols a me nā waikawa carboxylic. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui wahie ma muli o kona ʻike oxygen kiʻekiʻe. Loaʻa iā ia nā noi e pili ana i nā supercapacitors a me nā pila lithium.
He pani kūpono no ke kaiapuni no ka dimethyl sulfate, qv, a me methyl halides i nā hopena methylation a no ka phosgene, qv, i nā hopena methylcarbonylation.
ʻŌpala a me ka Hoʻouna ʻana
200KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
