1,4 butynediol wax soo saar sare oo adag
CAS: 110-65-6
Waxyaabaha kiimikada ee butynediol: crystal orthorhombic cad.Dhibicda dhalaalka 58 ℃, barta karkarinta 238 ℃, 145 ℃ (2KPa), barta toosh 152 ℃, index refractive 1.450.Ku milmay biyaha, xal acid, ethanol iyo acetone, wax yar ku milma chloroform, aan milmin benzene iyo ether.
Isticmaalka: butynediol waxaa loo isticmaali karaa in lagu soo saaro butene glycol, butynediol, n-butanol, dihydrofuran, tetrahydrofuran γ- Taxane ah badeecooyinka muhiimka ah ee organic sida butyrolactone iyo pyrrolidone ayaa sidoo kale loo isticmaali karaa si loo soo saaro balaastikada synthetic, fiilooyinka synthetic (nylon-4), maqaar macmal ah, daawo, sunta cayayaanka lagu dilo, dareerayaasha (N-methyl pyrrolidone) iyo waxyaalaha ilaaliya.Butynediol lafteedu waa dareere wanaagsan waxaana loo isticmaalaa sidii wax iftiimaya warshadaha korantada.
