Carbon tetrachloride

Carbon tetrachloride (CCl4) ne a colorless, nonflammable ruwa m refract hasken karfi. The abu yana da wani dadi wari. Carbon tetrachloride ma yana da wani narcotic sakamako. A al'ada yanayi, da zazzabi da kashi farfado sinadaran inertness. The abu ba amsa tare da ko dai acid (tare da mayar da hankali sulfuric acid, musamman), ko da kwasfansu. Tare da wannan, a fili interacts tare da mutum karafa quite m. A gaban ƙarfe ko aluminum, misali, carbon tetrachloride ya bazu a hankali a ruwa c bisa ga lissafi: CCl4 + 2H2O = CO2 + 4NS1. A wasu lokuta, a karkashin yanayinsa canji ba zai wani appreciable har.

Carbon tetrachloride. Properties

The rabo daga cikin abu 1,593, ruwan batu na 76,6 digiri. Abu solidifies a zazzabi na debe 22,87 digiri. Lokacin da debe 44,66 carbon tetrachloride yana da wani sauyin aya, da yin amfani da abin da aka bada shawarar ga k na thermometers.

The ruwa mai narkewa fili sosai dan kadan. A ashirin digiri a ɗaya da ɗari grams na ruwa da aka narkar da 0,08 grams na abu. A dielectric akai na carbon tetrachloride ne low isa (a goma sha takwas digiri - 2.3). A lokacin da wannan abu yana da babban haske refracting ikon. A Refractive index ga rawaya haske n = 1,463.

Don a carbon tetrachloride Properties hada da ikon na rushe da kwayoyin abubuwa. A madaidaci, abu ne gauraye da barasa da sauran ruwa kwayoyin halitta. A wannan connection, a fili amfani da ko'ina a vitro, domin fasaha dalilai kamar sauran ƙarfi resins, fats, mai da sauran abubuwa. Bugu da ƙari kuma, carbon tetrachloride amfani da lokacin da extinguishing gobara. The abu da ake amfani a magani a matsayin anthelmintic kuma m.

Daya samu a fili ta amfani da chlorination na carbon disulfide a gaban manganese chloride (II), ko kuma sauran m halogen. A sakamakon haka ne chlorous sulfur, wanda shi ne mafi kyau duka a gaban catalysts (FeS, misali), kuma a karkashin sakamakon matsakaici dumama (har zuwa game da sittin digiri) kuma reacts tare da carbon disulfide (CS2). Yana yiwuwa a gudanar da wani tsari don haka da cewa dauki zai ci gaba a layi daya. Sulfur precipitated a cikin tsari zai dawo zuwa ga farawa da aka gyara domin samun CS2. Tsarkakewa na carbon tetrachloride ne da za'ayi ta wanke tare da potassium hydroxide bayani, nan da nan ya bi ta hanyar fractional barasan aka yi.

Daya daga cikin manyan kalubale da ke fuskantar masana ne don zaɓar mafi m Hanyar aiki carbon tetrachloride. Gaggawa matsaloli nasaba yafi da cewa, bisa ga Montreal layinhantsaki, wannan abu da aka haramta saboda da hallakaswa sakamako a kan lemar sararin samaniya Layer.

Lokacin da kona fili ta amfani da iska a matsayin oxidant ake bukata domin man fetur samar lokaci guda dauri hydrogen chloride. Fuel wajibi ne ga kadan wadata. A gaban hydrogen chloride a cikin wani karamin adadin, shi za a iya tuba a cikin sodium chloride. Wannan shi ne zai yiwu ta alura sodium hydroxide bayani a cikin konewa gas. A wasu lokuta, da selection aka yi daga gas hydrogen chloride kamar yadda hydrochloric acid.

Wasu marubuta fi son da catalytic hadawan abu da iskar shaka. A kwatanta da kona carbon tetrachloride, a catalytic hadawan abu da iskar shaka tsari ne halin da hakan mataki na rage daraja na sharar gida organochlorine yanayi da aka ba tare da samuwar dioxins.
