Dimethyl sulfoxide CAS 67-68-5
ʻO ka dimethyl sulfide kahi pūhui polar ikaika ʻole protonated, no laila ʻaʻohe ona acidity a i ʻole alkalinity. Ma ka lumi wela, he wai kala ʻole me ka hygroscopicity. ʻAneʻane ʻala ʻole, me ka ʻono ʻawaʻawa. E hoʻoheheʻe i ka wai, ethanol, acetone, etera, benzene, a me ka chloroform. ʻO kēia huahana he alkaline nāwaliwali, paʻa ʻole i nā waikawa, a hana i nā paʻakai i ka wā e hālāwai ai me nā ʻakika ikaika. Hoʻoheheʻe ia i nā wela kiʻekiʻe a hana ikaika me ka chlorine, e hoʻopuka ana i kahi lapalapa uliuli māmā ke puhi ʻia i ka lewa.

Hoʻohana ʻia ʻo Dimethyl sulfide ma ke ʻano he analytical reagent a me ke kinoea chromatography stationary phase, a me ka solvent no ka nānā ʻana i nā spectroscopic UV. Hoʻohana ʻia ʻo ia ma ke ʻano he ʻano hana no ka hoʻoheheʻe ʻana i ka hydrocarbon aromatic, resin a me ka wai, he mea hoʻoheheʻe no ka polymerization acrylic, a me ke kiʻi kilika. Hiki ke hoʻohana ʻia ʻo Dimethyl sulfide ma ke ʻano he mea hoʻoheheʻe organik, ʻano hoʻohālikelike, a me waena o ka synthesis organik. Hoʻohana nui ʻia.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
