Madzi otumbululuka achikasu oopsa kwambiri 1,4-butynediol

Kufotokozera Kwachidule:

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.

1, 4 ntchito zazikulu za butynediol:kwa organic synthesis, yomwe imagwiritsidwa ntchito ngati chowunikira cha electroplating.

1,4-butynediol ingagwiritsidwe ntchito kupanga butene glycol, butanediol, 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 zotetezera.

Maonekedwe:kristalo woyera kapena wopepuka wachikasu wonyezimira (wowala wachikasu pambuyo pa kuyamwa chinyezi)_mfundo:58℃Boiling_point 238℃,145℃(2kPa)flash_ Point 152 ℃ refractive index 1.450 solubility sungunuka m'madzi, acid solution, ethanol pang'ono, ethanol chloroform, osasungunuka mu benzene ndi ether zinthu zina zolimba butynediol ndizosavuta kunyamulira mumlengalenga pa 25 ° C, zimakhala ndi mankhwala amowa oyipa kwambiri, komanso zimatha kuchitanso zina.

Zowopsa zakuthupi ndi zamankhwala:pakakhala kutentha kwakukulu, moto wotseguka kapena wothira okosijeni, pamakhala chiopsezo cha kuyaka ndi kuphulika chifukwa cha mikangano ndi mphamvu.Pa kutentha kwambiri, ngati waipitsidwa ndi mchere wa mercury, asidi wamphamvu, zitsulo zamchere zamchere, hydroxide ndi halide, kuphulika kungachitike.

Kusamala posungira:sungani m'nyumba yosungiramo zozizira komanso yolowera mpweya wabwino.Khalani kutali ndi moto ndi gwero la kutentha.Kusindikiza phukusi.Idzasungidwa mosiyana ndi ma oxidants, alkalis ndi mankhwala odyedwa, ndipo kusungirako kosakanikirana sikuloledwa.Zowunikira zotsimikizira kuphulika ndi malo olowera mpweya wabwino ziyenera kulandiridwa.Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kutulutsa zopsereza.Malo osungiramo zinthu ayenera kukhala ndi zipangizo zoyenera kuti zikhale ndi kutayikira.

Malingaliro a kampani Henan Haiyuan Fine Chemical Co., Ltd.1,4-butynediol yolimba, yatsopano yopanda deliquescence, yabwino kwambiri.

Zam'mbuyo: 1,4 butynediol cholimba chapamwamba kwambiri
