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 i ngā ether me ngā esters, ka taea te waikura hei whakaputa i ngā aldehydes, i ngā waikawa rānei, ā, ka taea te whakapūmau hei whakaputa i ngā ethers.

Āhua: wai kore tae, mārama, matotoru.

Ngā Whakamahinga: Ko te ethylene glycol te nuinga o te wā 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 kāore i te 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, te dinitroethylene glycol, he mea pahū. Ka taea e te ethylene glycol te whakaheke i te pae tio o ngā wairewa wai, nō reira ka whakamahia pinepinetia hei ārai tio.
