thepa ya moaho
1,4-Butanediol ke mokelikeli o mafura o se nang 'mala o nang le sebaka se chesang se chesang sa 20.1°C. Sebaka se belang 235 ℃. Ntlha ea Flash (kopi e bulehileng) 121℃. Boima ba kamano d 4201.0171. index ea refractive nD201.4461. viscosity (25 ℃) 71.5mPa-s. hygroscopic. E kopane le metsi, e qhibilihang ka har'a methanol, ethanol, acetone, e qhibilihang hanyane ka har'a ether.
Lik'hemik'hale
Ka reactivity e matla, e ka etsa oxidation, dehydration, replacement, polymerization, amination, esterification, halogenation le liphetoho tse ling tsa lik'hemik'hale ho hlahisa letoto la lihlahisoa tsa bohlokoa tsa lik'hemik'hale. Ketone, e qhibilihang hanyane ka har'a ether.
Ts'ebetso ea tlhahiso
E entsoe ka acetylene le formaldehyde ka boteng ba catalyst ho etsa 1,4-butynediol, 'me joale catalytic hydrogenation. E ka boela ea etsoa ho tloha 1,3-butadiene ka acetic acid le oksijene ka acetyl oxidation, hydrogenation, hydrolysis le liketso tse ling.
Ho paka le ho boloka le ho tsamaisa
E pakiloeng ka aluminium, libarele tsa masenke kapa libarele tsa polasetiki, kapa e bolokoa le ho tsamaisoa ka literaka tsa litanka e le thepa e tukang le e chefo. Kaha sebaka se qhibilihang se ka holimo ho 20 ℃, tanka e lokela ho ba le li-tube tse futhumatsang.
