Dimethyl sulfoxide CAS 67-68-5
Ko te Dimethyl sulfide he puhui polar tino kore protonated, na reira karekau he waikawa, kawakore ranei. I te pāmahana rūma, he wai kore tae me te hygroscopicity. Tata kore kakara, he kawa te reka. Whakarewa i roto i te wai, te waiwaro, te acetone, te etera, te benzene, me te chloroform. He ngoikore te kawakore o tenei hua, karekau ki te waikawa, ka hanga tote ina tutaki ki nga waikawa kaha. Ka pirau i te wera nui, ka kaha te tauhohe ki te maota, ka puta he mura kikorangi ina tahuna ki te hau.

Ka whakamahia te Dimethyl sulfide hei reagent tātari me te wahanga chromatography hau, tae atu ki te whakarewa mo te tātari spectroscopic UV. Ka whakamahia ano hei reo tauhohenga mo te tangohanga waiwaro kakara, te kapia me te tae, he whakarewa mo te polymerization kiriaku, me te tuhi hiraka. Ka taea te whakamahi i te Dimethyl sulfide hei whakarewa pararopi, te reo tauhohenga, me te takawaenga i roto i te whakahiato waro. Ka whakamahia whānuitia.
I te nuinga o te waa ka whakakiia ki te 25kg / pahū, ka taea hoki te mahi mo te kete.
