Taw qhia
γ-crotonyllactone (GBL) yog cov organic compound. Cov hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb ntawm GBL:
Zoo:
Cov tsos mob: Cov xim tsis muaj xim pob tshab nrog cov ntxhiab tsw zoo li ethanol.
Qhov ceev: 1.125 g / cm³
Solubility: Soluble nyob rau hauv ntau cov organic solvents, xws li dej, cawv, ether, thiab lwm yam.
Siv:
Kev siv: GBL yog dav siv los ua surfactant, dye solvent, resin solvent, yas hnyav, tu tus neeg saib xyuas, thiab lwm yam.
Txoj kev:
GBL tuaj yeem tau txais los ntawm oxidizing crotonone (1,4-butanol). Txoj kev npaj tshwj xeeb yog los ua crotonone nrog cov roj chlorine los tsim 1,4-butanedione, thiab tom qab ntawd hydrogenate 1,4-butanedione nrog NaOH los tsim GBL.
Cov ntaub ntawv kev nyab xeeb:
GBL muaj cov yam ntxwv ntawm kev hloov pauv siab thiab yooj yim nqus ntawm daim tawv nqaij thiab cov mucous daim nyias nyias, thiab muaj qee yam toxicity rau tib neeg lub cev. Siv ceev faj.
GBL tuaj yeem cuam tshuam rau hauv nruab nrab lub paj hlwb, thiab ntau npaum li cas yuav ua rau muaj kev cuam tshuam xws li kiv taub hau, tsaug zog, thiab cov leeg tsis muaj zog. Ua raws li cov kev cai lij choj thiab cov cai.
