1,4 butynediol paʻa huahana ʻoi aku ka maikaʻi
CAS:110-65-6
Nā waiwai kemika o butynediol: keokeo orthorhombic kristal.ʻO ka helu heheʻe 58 ℃, kahi e hoʻolapalapa ai 238 ℃, 145 ℃ (2KPa), kiko uila 152 ℃, helu kuhikuhi refractive 1.450.Hiki ke hoʻoheheʻe ʻia i loko o ka wai, ka hopena waika, ka ethanol a me ka acetone, hiki ke hoʻoheheʻe iki ʻia i ka chloroform, hiki ʻole ke hoʻoheheʻe ʻia i ka benzene a me ka etera.
Hoʻohana: hiki ke hoʻohana ʻia ka butynediol e hana i ka butene glycol, butynediol, n-butanol, dihydrofuran, tetrahydrofuran γ- Hiki ke hoʻohana hou ʻia ke ʻano o nā huahana organik koʻikoʻi e like me butyrolactone a me pyrrolidone e hana i nā plastic synthetic, synthetic fibers (nylon-4), ʻili hana, lāʻau lapaʻau, pesticides, solvents (N-methyl pyrrolidone) a me nā mea mālama.He mea hoʻoheheʻe maikaʻi ʻo Butynediol a hoʻohana ʻia e like me ka mea hoʻomālamalama i ka ʻoihana electroplating.

ʻO ka wai ʻawaʻawa ʻoi loa ka huahana propargyl alcoho
Wai waihoʻoluʻu ʻole me ka ʻala ʻala.He mea maʻalahi ke huli melemele ke waiho ʻia no ka manawa lōʻihi, ʻoi aku ka maikaʻi ke ʻike ʻia i ka mālamalama.Hiki ke hui me ka wai, benzene, chloroform, 1,2-dichloroethane, etera, ethanol, acetone, dioxane, tetrahydrofuran a me pyridine, hiki ke hoʻoheheʻe ʻia i loko o ka carbon tetrachloride, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka aliphatic hydrocarbons.
Nā Huahana a pau
Hana kūikawā i ka hana ʻana i ka waiʻona propargyl, 1,4 butynediol a me 3-chloropropyne
