1,4 butynediol yakasimba yepamusoro chigadzirwa
CAS:110-65-6
Kemikari zvimiro zve butynediol: chena orthorhombic crystal.Melting point 58 ℃, 238 ℃, 145 ℃ (2KPa), flash point 152 ℃, refractive index 1.450.Soluble mumvura, acid solution, ethanol uye acetone, inonyungudika zvishoma muchloroform, isinganyunguriki mubenzene uye ether.
Kushandiswa: butynediol inogona kushandiswa kugadzira butene glycol, butynediol, n-butanol, dihydrofuran, tetrahydrofuran γ- Mutsara wezvinhu zvakakosha zvehupenyu zvakadai sebutyrolactone uye pyrrolidone zvinogona kushandiswa zvakare kugadzira mapurasitiki ekugadzira, synthetic fibers (nylon-4), dehwe rekugadzira, mushonga, mishonga yezvipembenene, zvinonyungudutsa (N-methyl pyrrolidone) uye zvinodzivirira.Butynediol pachayo inonyungudutsa yakanaka uye inoshandiswa seyakajeka muindasitiri ye electroplating.
