Imikhiqizo

Izithasiselo ezenziwe ngokwezifiso ziyinhlanganisela yamakhemikhali ekhethekile eklanyelwe ukuhlangabezana nezidingo ezithile kanye nezidingo zezimboni ezihlukahlukene, okuhlanganisa amapulasitiki, ukudla, imithi, kanye nezimonyo. Lezi zengezo zithuthukisa ukusebenza, ukuzinza, kanye nokubukeka kwemikhiqizo yokugcina ngokuthuthukisa izakhiwo ezifana nokuqina, ukuguquguquka, ukuzinza kwe-thermal, nempilo yeshalofu.
Themba i-Dotachem ukuletha izixazululo ezenziwe ngokwezifiso ezihlukanisa imikhiqizo yakho.

I-Methyl acetate, eyaziwa nangokuthi i-MeOAc, i-acetic acid methyl ester noma i-methyl ethanoate, uketshezi olungenambala, inephunga elimnandi. Kuyi-acetate eyakhiwe yi-condensation ye-acetic acid ne-methanol. Ukusetshenziswa okuyinhloko kwe-methyl acetate kunjenge-solvent eguquguqukayo, enobuthi obuphansi kumaglue, opende, nezihlanzi ze-nail polish. Thola imininingwane yomkhiqizo ukuze uqinisekise ukuthi imikhiqizo yethu ingasetshenziswa ngokuphelele enqubweni yakho yezimboni!

I-Ethyl acetate iwuketshezi olungenambala olunokunambitheka okuguquguqukayo, okunezithelo. Kuyi-solvent esetshenziswa kabanzi, ikakhulukazi amapende, ama-varnish, ama-lacquers, izingxube zokuhlanza namakha. I-Ethyl acetate ixubene nezinyibilikisi eziningi eziphilayo futhi ingasetshenziswa ekuhlanzeni izingxube ukuze kukhishwe uwoyela, amafutha kanye nomhlabathi.

I-Butyl acetate iwuketshezi olungenambala olunephunga elimnandi. I-Butyl acetate inyibilika kancane emanzini futhi ingaxubana notshwala, i-ether nezinye izinyibilikisi ezivamile zemvelo. Uma iqhathaniswa ne-homologue yayo ephansi, i-butyl acetate ayincibiliki kalula emanzini futhi kunzima kakhulu ukuyikhipha emanzini. Kodwa-ke, ngaphansi kwesenzo se-acids noma izisekelo, i-acetic acid ne-butanol i-hydrolyzed. I-Butyl acetate iyi-solvent ephakathi nendawo ebaluleke kakhulu embonini yokumboza.

I-Tetrachloroethene iwuketshezi olungenambala olunephunga elifana ne-ether futhi lungancibilikisa izinto ezihlukahlukene. Isetshenziswa kakhulu ekuhlanzeni okomile kwezindwangu kanye nokukhishwa kwezinsimbi, nasekukhiqizeni amanye amakhemikhali.

I-Propionic acid iwuketshezi olungenambala olunephunga elikhuthazayo. I-Propionic acid i-short-chain saturated fatty acid, ene-asidi ebuthakathaka esisombululo esinamanzi, kodwa igqwala kakhulu, futhi umhwamuko uyacasula esikhumbeni nasemgudwini wokuphefumula. Kuyi-organic synthetic impahla eluhlaza, esetshenziselwa ikakhulukazi ukuhlanganiswa kwemikhiqizo ye-propionate ne-ester.
