Dimethyl sulfoxide CAS 67-68-5
He hui polar ikaika ʻole ka Dimethyl sulfide 67-68-5, no laila ʻaʻohe ona acidity a alkalinity paha. Ma ka mahana o ka lumi, he wai kala ʻole ka DMSO me ka hygroscopicity. Kokoke ʻaʻohe ʻala, me ka ʻono ʻawaʻawa. Hoʻoheheʻe ʻia i loko o ka wai, ethanol, acetone, ether, benzene, a me chloroform. He alkaline nāwaliwali ka Dimethyl sulfoxide DMSO, paʻa ʻole i nā waikawa, a hana i nā paʻakai ke hālāwai me nā waikawa ikaika. Hoʻopau ʻo Dimethyl sulfoxide DMSO i nā mahana kiʻekiʻe a pane ikaika me ka chlorine, e hoʻopuka ana i kahi lapalapa polū māmā ke puhi ʻia i ka lewa.

Hoʻohana ʻia ʻo Dimethyl sulfide ma ke ʻano he reagent analytical a me ka gas chromatography stationary phase, a me kahi solvent no ka nānā ʻana i ka spectroscopic UV. Hoʻohana pū ʻia ʻo Dimethyl sulfoxide DMSO ma ke ʻano he medium reaction no ka aromatic hydrocarbon extraction, resin a me dye, kahi solvent no ka acrylic polymerization, a me ke kaha kiʻi silika. Hiki ke hoʻohana ʻia ʻo Dimethyl sulfide ma ke ʻano he solvent organic, reaction medium, a me ka intermediate i ka synthesis organic. Hoʻohana nui ʻia.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
