1,4 butynediol cholimba chapamwamba kwambiri
CAS: 110-65-6
Chemical katundu wa butynediol: woyera orthorhombic crystal.Malo osungunuka 58 ℃, otentha 238 ℃, 145 ℃ (2KPa), flash point 152 ℃, refractive index 1.450.Amasungunuka m'madzi, asidi, ethanol ndi acetone, amasungunuka pang'ono mu chloroform, osasungunuka mu benzene ndi ether.
Kagwiritsidwe: butynediol ikhoza kugwiritsidwa ntchito kupanga butene glycol, butynediol, n-butanol, dihydrofuran, tetrahydrofuran γ- Mndandanda wa zinthu zofunika kwambiri zamoyo monga butyrolactone ndi pyrrolidone zingagwiritsidwe ntchito popanga mapulasitiki opangidwa, nylon-4), zikopa zopangira, mankhwala, mankhwala ophera tizilombo, zosungunulira (N-methyl pyrrolidone) ndi zoteteza.Butynediol palokha ndi zosungunulira zabwino ndipo amagwiritsidwa ntchito ngati kuwala mu makampani electroplating.

Madzi otumbululuka achikasu oopsa kwambiri 1,4-butynediol
1,4-butynediol olimba, mankhwala chilinganizo C4H6O2, woyera orthorhombic crystal.Amasungunuka m'madzi, asidi, ethanol ndi acetone, osasungunuka mu benzene ndi ether.Ikhoza kukhumudwitsa mucous nembanemba, khungu ndi chapamwamba kupuma thirakiti maso.M'makampani, 1,4-butynediol yolimba imakonzedwa makamaka ndi njira ya Reppe, yopangidwa ndi butynediol mkuwa kapena copper bismuth chothandizira, ndipo imakonzedwa ndikuchita kwa acetylene ndi formaldehyde popanikizika (1 ~ 20 bar) ndi kutentha (110 ~ 112 ° C) .Butynediol yaiwisi imapezeka mwa kuchitapo kanthu, ndipo chomalizidwacho chimapezeka kudzera mu ndende ndi kuyenga.

Zamadzimadzi oopsa kwambiri kuposa mowa wa propargyl
Madzi opanda mtundu, osasunthika komanso onunkhira.N'zosavuta kutembenukira chikasu pamene aikidwa kwa nthawi yaitali, makamaka pamene kuwala.Ndi miscible ndi madzi, benzene, chloroform, 1,2-dichloroethane, ether, ethanol, acetone, dioxane, tetrahydrofuran ndi pyridine, sungunuka pang'ono mu carbon tetrachloride, koma osasungunuka mu aliphatic hydrocarbons.
Zogulitsa Zonse
Okhazikika pakupanga mowa wa propargyl, 1,4 butynediol ndi 3-chloropropyne
