Timphahla Letivamile Tetjwala
Tjwala buyintfo lete umbala, lebonakalako, legucugucukako, levutsako, futsi lengadvonsi. Ineliphunga lelifana neliwayini, kunambitseka lokubuhlungu nalokubabako, kanye nekunambitseka lokumnandzi kancane ngemuva kwaloko. Ligama layo lesayensi yi-ethanol, lenefomula yemamolekhyuli C2H5OH. Ibitwa ngekutsi “tjwala” ngoba sakhiwo sayo se molecule sicuketse licembu le hydroxyl (-OH).
Indzawo yekubandza: ~-114°C
Liphuzu lekubila: 78.3°C
Ingahlangana nemanti, i-ether, i-chloroform, kanye naletinye tintfo letiphilako letincibilikisako kunobe ngusiphi silinganiso futsi i-hygroscopic, yakha tihlanganisi te-azeotropic nemanti.
Umhwamuko we ethanol ungakha tihlanganisi letiqhumako nemoya, ngemkhawulo wekuqhuma emoyeni.
Ngekuhlanganiswa kwa 70% (v/v), tjwala bunemtselela locinile wekubulala emagciwane futsi bungaphindze busetjentiswe njengekugcina kanye nekuncibilikisa.
Esimeni lesibucayi kakhulu (243°C, 60 kg/cm2), i-ethanol ikhombisa kucibilika lokucinile kakhulu, kwenta kutsi kukhishwe emanti labucayi kakhulu.
Ngenca yendzawo yayo lephansi yekubandza, tisombululo te tjwala letinekuhlanganiswa lokutsite tingasetjentiswa njenge antifreeze kanye netifriji.
I-Ethanol ingatsatsa sikhundla saphethiloli njengephethiloli, kwenta kutsi kube ngumtfombo wemandla lavuselelwako.

- Singeniso Semkhicito We-Ethanol
I-Shandong Pulisi Chemical Co., Ltd. ngumkhiciti wemakhemikhali lofundzele umsebenti kanye nemtsengisi losebenta eShandong, eShayina, lokhetsekile ekukhiciteni nasekuphakeleni kwemhlaba wonkhe kwe-ethanol yetimboni lesezingeni leliphakeme (tjwala be-ethyl, C2H5OH). Ngetinsita tekukhicita letisezingeni lelisetulu, tinhlelo tekulawula lizinga leticinile, kanye nesipiliyoni lesicebile ekuhwebeni kwemave emhlaba, siniketa tisombululo te-ethanol letetsembekile etimbonini emhlabeni wonkhe, kufaka ekhatsi imitsi, timonyo, kucubungula kudla, emakhemikhali etimboni, kanye nemikhakha yemandla.
