BDO, Yakakosha yakakosha organic kemikari uye yakanaka makemikari mbishi zvinhu, yakagadziridzwa zasi kwemvura, uye inogona kushandiswa kugadzira anopfuura mazana maviri emarudzi ezvigadzirwa zvemakemikari akanaka.
BDO, Yakakosha yakakosha organic makemikari uye yakanaka makemikari mbishi zvinhu, yakagadziridzwa yakadzika, uye inogona kushandiswa kugadzira anopfuura mazana maviri emhando yezvigadzirwa zvemakemikari zvakanaka, zvinosanganisira minda yakawanda, yakadai sekugadzira mota, midziyo yemagetsi nemagetsi, kutaurirana ruzivo, engineering mapurasitiki, zvekuvaka, michina, petrochemical, machira, mushonga, kudhinda, zvizorwa uye zvichingodaro.
Physical properties
1,4-Butanediol imvura isina ruvara ine mafuta uye inopisa inonyunguduka inosvika 20.1°C. Boiling point 235 ℃. Flash point (kapu yakazaruka) 121℃. Relative density d 4201.0171. refractive index nD201.4461. viscosity (25 ℃) 71.5mPa-s. hygroscopic. Kusanganiswa nemvura, soluble mu methanol, ethanol, acetone, zvishoma soluble mu ether.
Makemikari zvinhu
Iine reactivity yakasimba, inogona kuita oxidation, dehydration, kutsiva, polymerization, amination, esterification, halogenation uye mamwe maitiro emakemikari kugadzira akateedzana akakosha emakemikari zvigadzirwa. Ketone, inonyungudika zvishoma muether.
Muitiro wekugadzira
Yakagadzirwa kubva kuacetylene uye formaldehyde pamberi peiyo catalyst yekugadzira 1,4-butynediol, uyezve catalytic hydrogenation. Inogonawo kugadzirwa kubva ku1,3-butadiene neacetic acid uye oksijeni neacetyl oxidation, hydrogenation, hydrolysis uye mamwe maitiro.
Kurongedza uye kuchengetedza uye kutakura
Iyo yakazara mualuminium, galvanized iron barrels kana epurasitiki mbiya, kana kuchengetwa uye kutakurwa mumarori ekutakura zvinhu sezvinhu zvinopfuta uye zvine chepfu. Nekuti nzvimbo yekunyunguduka yakakwira se20 ℃, tanker inofanirwa kunge ine yekudziya chubhu.
shandisa
1,4-Butanediol inoshandiswa zvakanyanya mukugadzirwa kwe polybutylene terephthalate (PBT), tetrahydrofuran (THF), gamma-butyrolactone (GBL), N-methyl-pyrrolidone (NMP), N-vinylpyrrolidone (NVP), polyurethane resin (PU). ) uye yepamusoro-soro elastic fiber SPANDEX (spandex), nemamwe makemikari akanaka ane kukosha kwakawedzerwa. Inoshandiswa zvakanyanya sezvinonyungudutsa, mishonga uye zvizorwa, plasticizers, kurapa, mishonga yezvipembenene, mishonga yesora, furo rematehwe, faibha, engineering mapurasitiki, nezvimwe.
