Tshwj xeeb hauv kev tsim cov cawv propargyl, 1,4 butynediol thiab 3-chloropropyne

daj ntseg daj kua kua 1,4-butynediol

Lus piav qhia luv luv:

1,4-butynediol khoom, tshuaj formula C4H6O2, dawb orthorhombic siv lead ua.Soluble nyob rau hauv dej, acid, ethanol thiab acetone, insoluble nyob rau hauv benzene thiab ether.Nws tuaj yeem ua rau khaus ntawm daim tawv nqaij, tawv nqaij thiab ua pa ntawm lub qhov muag.Hauv kev lag luam, 1,4-butynediol khoom yog npaj los ntawm Reppe txoj kev, catalyzed los ntawm butynediol tooj liab los yog tooj liab bismuth catalyst, thiab npaj los ntawm cov tshuaj tiv thaiv ntawm acetylene thiab formaldehyde nyob rau hauv siab (1 ~ 20 bar) thiab cua sov (110 ~ 112 ° C) .Lub crude butynediol yog tau los ntawm cov tshuaj tiv thaiv, thiab cov khoom tiav yog tau los ntawm concentration thiab refining.

Product Description

1, 4 butynediol lub ntsiab siv:rau organic synthesis, siv los ua electroplating brightener.

1,4-butynediol tuaj yeem siv los tsim butene glycol, butanediol, n-butanol, dihydrofuran, tetrahydrofuran γ- Cov khoom lag luam tseem ceeb xws li butyrolactone thiab pyrrolidone tuaj yeem siv ntxiv los tsim cov khoom siv hluavtaws, hluavtaws fibers (nylon-4. ), tawv tawv, tshuaj, tshuaj tua kab, cov kuab tshuaj (N-methyl pyrrolidone) thiab tshuaj tua kab mob.

Qhov tsos:Dawb los yog lub teeb daj siv lead ua dawb rhombic siv lead ua (lub teeb daj tom qab nqus dej) _ point: 58 ℃ Boiling_ point 238 ℃ , 145 ℃ (2kPa) flash_ Point 152 ℃ refractive index 1.450 solubility soluble hauv dej, kua qaub, ethanol thiab me ntsis soluble hauv chloroform, insoluble nyob rau hauv benzene thiab ether lwm yam khoom muaj zog butynediol yog ib qho yooj yim rau deliquesce nyob rau hauv cov huab cua ntawm 25 ° C, muaj cov tshuaj muaj pes tsawg leeg ntawm binary thawj cawv, thiab muaj peev xwm nqa tawm ntxiv cov tshuaj tiv thaiv.

Kev phom sij rau lub cev thiab tshuaj lom neeg:Thaum tshav kub kub, qhib hluav taws los yog tov nrog oxidant, muaj kev pheej hmoo ntawm combustion thiab tawg los ntawm kev sib txhuam thiab kev cuam tshuam.Thaum kub kub, yog tias nws muaj kuab paug los ntawm mercury ntsev, muaj zog acid, alkaline ntiaj teb hlau, hydroxide thiab halide, tawg yuav tshwm sim.

Kev ceev faj cia:khaws cia rau hauv ib qho chaw txias thiab ventilated warehouse.Khaws kom deb ntawm qhov hluav taws kub thiab qhov cua sov.Ntim sealing.Nws yuav tsum tau muab cais los ntawm oxidants, alkalis thiab edible tshuaj, thiab sib tov cia yuav tsum tsis txhob tso cai.Kev tawg pov thawj teeb pom kev zoo thiab qhov cua qhov chaw yuav tsum tau txais yuav.Nws yog txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov txim taws.Lub chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov dej xau.

Cov khoom siv ntawm Henan Haiyuan Fine Chemical Co., Ltd.:1,4-butynediol khoom, tshiab tsis muaj deliquescence, zoo heev.
