1,4 butynediol malosi sili oloa
CAS:110-65-6
O mea tau vaila'au o le butynediol: tioata orthorhombic pa'epa'e.Liu liusuavai 58 ℃, vevela 238 ℃, 145 ℃ (2KPa), moli moli 152 ℃, fa'asino fa'asino 1.450.Solu i le vai, vaifofo acid, ethanol ma acetone, soluble teisi i chloroform, le mafai ona solu i benzene ma eter.
Faʻaaogaina: butynediol e mafai ona faʻaaogaina e gaosia ai le butene glycol, butynediol, n-butanol, dihydrofuran, tetrahydrofuran γ- O se faasologa o mea taua faʻaletino e pei ole butyrolactone ma pyrrolidone e mafai ona faʻaogaina atili e gaosia ai palasitisi faʻapipiʻi, filo synthetic (nylon-4), pa'u fa'akomepiuta, vaila'au, vaila'au fa'atosina, solvents (N-methyl pyrrolidone) ma fa'asao.Butynediol lava ia o se solvent lelei ma e faʻaaogaina e fai ma faʻamalamalamaga i le eletise eletise.
