I-Polyvinyl Alcohol

Incazelo emfushane:

I-Polyvinyl alcohol iyinhlanganisela yemvelo, ifomula yamakhemikhali ithi [C2H4O]n, ukubukeka kungama-flake amhlophe, okuqinile noma okuyimpuphu okuqinile, akunaphunga. Incibilika emanzini (ngaphezu kuka-95℃), incibilika kancane ku-dimethyl sulfoxide, ayincibiliki kuphethiloli, uphalafini, uwoyela wemifino, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, njll. I-polyvinyl alcohol ibalulekile. izinto zokusetshenziswa zamakhemikhali ezisetshenziswa ekwenzeni ama-acetal e-polyvinyl, amapayipi angavimbeli uphethiloli kanye nama-vinylans, ama-ejenti okwelapha izindwangu, ama-emulsifiers, okokumboza amaphepha, okunamathelayo, iglue, njll.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Incazelo Yomkhiqizo

I-Cyclopentanone, i-organic compound, i-chemical formula C5H8O, uketshezi olungenambala, olungancibiliki emanzini, oluncibilika ku-ethanol, i-ether, i-acetone nezinye izincibilikisi eziphilayo, ikakhulukazi ezisetshenziswa njengezidakamizwa, imikhiqizo yebhayoloji, izibulala-zinambuzane kanye nezithako zenjoloba zokwenziwa.

Isicelo

Ingumgqugquzeli we-photosynthesis yezitshalo, ebuye isetshenziswe njengezithasiselo zokudla kwemfuyo, ikhuthaze ukukhiqizwa kwamaqanda kanye nodoti.
