ʻO Dimethyl sulfoxide (DMSO pōkole) kahi hui organik i loaʻa ka sulfur; ʻo ke ʻano molekala: (CH3) 2SO; Hōʻike ia he wai aniani ʻole, ʻala ʻole, hygroscopic a me ka ʻā ʻana i ka mahana o ka lumi. Loaʻa iā ia ka polarity kiʻekiʻe a me ke kiko paila kiʻekiʻe. Loaʻa iā ia nā ʻano aprotic a me ka wai-miscible. He haʻahaʻa ka toxicity, kūpaʻa thermal maikaʻi, a ʻaʻole hiki ke hui pū me ka paraffin. Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, propanol, ether, benzene a me chloroform a me nā ʻano mea organik ʻē aʻe a ua kapa ʻia ʻo ia ʻo "solvent universal." He mea hoʻoheheʻe organik maʻamau ia nona ka hiki ke hoʻoheheʻe ikaika loa. Hiki iā ia ke hoʻoheheʻe i ka hapa nui o nā hui organik e pili ana i nā carbohydrates, polymers, peptides, a me nā paʻakai inorganic a me nā kinoea. Hiki iā ia ke hoʻoheheʻe i kahi nui o ka solute nona ke kaumaha he 50-60% o ia iho (ʻo nā mea hoʻoheheʻe maʻamau ʻē aʻe e hoʻoheheʻe wale i ka 10-20%), no laila he mea nui loa ia i ka hoʻokele laʻana a me ka nānā wikiwiki ʻana i nā lāʻau lapaʻau. Ma lalo o kekahi mau kūlana, hiki i ka hoʻopili ʻana ma waena o ka dimethyl sulfoxide a me ka chloride ke alakaʻi i kahi hopena pahū.

Hoʻohana
1. Hiki ke hoʻohana ʻia no ka unuhi ʻana o ka arene, a ma ke ʻano he mea hoʻohuihui i hoʻohana ʻia no nā resins a me nā dyes, a hoʻopili ʻia i ka polymerization acrylic a me ka sliding solvent.
2. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe organik, mea hana a me nā mea waena o ka synthesis organik. He mea maʻalahi loa ia. Loaʻa i kēia huahana kahi mana hoʻopuka koho kiʻekiʻe, a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe polymerization a me ka condensation o ka acrylic resin a me ka polysulfone resin, ma ke ʻano he mea hoʻoheheʻe polymerization a me ka milo o ka polyacrylonitrile a me ka cellulose acetate, ma ke ʻano he mea hoʻoheheʻe no ka hoʻokaʻawale ʻana i nā alkanes a me nā arenes, a ma ke ʻano he mea hana no nā arenes, ka hoʻoheheʻe butadiene, ka fiber acrylic, nā mea hoʻoheheʻe plastik, nā mea hoʻoheheʻe organik a me synthetic, a me nā ʻoihana lāʻau lapaʻau. Ma ke kahua o ka lāʻau lapaʻau, loaʻa i ka dimethyl sulfoxide ka hopena anti-inflammatory a me ka analgesic me ka hiki ke komo ma o ka ʻili, a no laila hiki ke hoʻoheheʻe i kekahi mau lāʻau lapaʻau a hoʻonui i ko lākou komo ʻana i loko o ke kino o ke kanaka e hoʻokō i nā kumu therapeutic. ʻO ka lawe ʻana i kēia waiwai lawe o ka dimethyl sulfoxide hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui pesticide. ʻO ka hoʻohui ʻana i kahi liʻiliʻi o ka dimethyl sulfoxide i loko o kekahi mau pesticides hiki ke hoʻomaʻamaʻa i ke komo ʻana o nā pesticides i loko o ka mea kanu i mea e hoʻomaikaʻi ai i ka pono. Hiki ke hoʻohana ʻia ka dimethyl sulfoxide ma ke ʻano he mea hoʻoheheʻe dye, mea wehe dye, a me ka mea lawe dye no nā fibers synthetic. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopū i ka acetylene hana hou a me ka sulfur dioxide a me nā mea hoʻololi o ka fiber synthetic, antifreeze agent a me ka capacitor dielectric, brake oil, a me ka extractant o nā metala laha ʻole.
3. Hiki ke hoʻohana ʻia ma ke ʻano he mau mea hoʻoheheʻe analytic a me ka mea hoʻopaʻa o ka chromatography kinoea a me ka mea hoʻoheheʻe no ka nānā ʻana i nā spectra UV.

225KG/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.
