CAS 107-21-1 Ethylene glycole glycole glycoles glycole glycoles glycolediol, yog cov lus nrov organic qhia tias nws yog ib pawg organic tau qhia meej, yog muaj kev lom zem rau cov phooj ywg. Yog li, glycol ua cawv yog cov kua tsis muaj kob uas muaj viscosity siab thiab qab qab. Ntxiv rau nws qhov zoo tshaj tawm nrog dej, nws tseem yog soluble nyob rau hauv Aldehydes, ketones thiab acetic acid, tab sis nws tsis yaj txhua hauv carbon tetrachloride.

Ethylene glycol siv
Nws cov ntawv thov tseem ceeb yog nyob rau hauv kev tsim polyester fibers thiab cov ntaub ntawv cob qhia (rau cov ntawv sau tshuaj, thiab siv cov tshuaj tiv thaiv kev lag luam), ua yeeb yam ua haujlwm rau lwm cov glycols thiab tshuaj tshwj xeeb. Ethylene glycol (meg) kuj ua haujlwm ua lub cev qhuav dej hauv kev ua kom muaj ntuj ua thiab khov}
