Etirene glycol CAS 107-21-1

Ko te Ethylene glycol, e mōhiotia ana ko te glycol, te diol aliphatic māmā rawa atu. He rite ōna āhuatanga matū ki ngā waipiro, pērā i te kaha ki te whakaputa ethers me ngā esters, ki te whakapūngao hei whakaputa aldehydes, waikawa rānei, me te whakapūngao hei whakaputa ethers. Ka taea hoki te whakakapi ki ngā halogens. Ina tauhohe ki ngā acyl chlorides, ki ngā anhydrides waikawa rānei, ka hangaia ngā diesters. Ina werahia i te aroaro o tētahi catalyst (te konupora hauhā, te konupora waikura, te konutea waikura, te waikawa whanariki rānei), ka taea te whakamaroke i roto i ngā ngota ngota, i waenga rānei i ngā ngota ngota hei whakaputa i te cyclic ethylene glycol acetal, e tauhohe ana ki te waikawa hauota hei whakaputa i te ethylene glycol dinitrate (he pahūtanga). He rauemi mata te Ethylene glycol mō te hanga kapia polyester, ngā kapia alkyd, me ngā muka polyester. Ka whakamahia hoki hei ārai hukapapa mō ngā motuka me ngā miihini rererangi.

Āhua: Wai kore tae, mārama, matotoru

Ngā Whakamahinga Ko te ethylene glycol te mea matua e whakamahia ana hei rauemi mata mō ngā muka polyester, ā, e whakamahia ana hoki i roto i ētahi atu kapia polyester, ngā kapia polyester kore mākū me ngā peita polyester 1730. Ka taea te hanga i ngā momo surfactants mai i te ethylene glycol me te polyethylene glycol. Ko tōna matū dinitro ko te dinitroethylene glycol he mea pahū. Ka taea e te ethylene glycol te whakaheke i te pae tio o ngā wairewa wai, nō reira he maha ngā wā e whakamahia ana hei rongoā ārai tio.
