Benzyl Alcohol: Properties, Nkwadebe, ngwa

Aromatic alcohols - benzene homologues nkwekọrịta, na buu nke hydrogen atọm na-anọchi hydroxy. Ugbu a, senti ụlọ ọrụ na-ukwuu na-eji benzyl mmanya. The usoro nke compound ahụ nọchiri anya ya buu fọduru nke ihe mmanya na benzene (phenyl) - S6N5SN2ON. Aromatic alcohols ji isomerism buu n'akụkụ yinye na pụrụ isi chọta otu - OH na hydrocarbon yinye. Mmanya na ọtụtụ nke ikpe, nyere ihe na-enweghị aha.

Benzyl mmanya: ụzọ nke na-

Aromatic alcohols na free steeti a na ekesa ke uwa. Dị ka a na-achị, ha na-ahụrụ na mkpa mmanụ. Benzyl mmanya e synthesized si halogenated benzene homologues, nke halogen na-metụtara nanị akụkụ ụfọdụ na a n'akụkụ yinye. Ndị a alcohols si dị iche na phenols n'elu niile n'ihi na ha na-adịghị akpọ acidic Njirimara. Benzyl mmanya na-enwetara site eke ngwaọrụ, nke nwere esters. Mgbe nke ahụ gasịrị, ọ na-enweta na-amịpụtara na aromatic alcohols. Aromatic alcohols bụ nnọọ nso aliphatic alcohols: site n'oru nke alkali metal alkoxides etolite; site ọxịdashọn, dabere na Ọdịdị, ọ na-ghọrọ ka kwekọrọ ekwekọ aldehydes ma ọ bụ ketones; Ọ dị mfe ụdị ethers na esters.

Physical Njirimara nke alcohols

The mbụ nnọchiteanya nke ndị homologous usoro nke acyclic alcohols - mmiri mmiri, na elu alcohols - solids. First homologs (methanol, ethanol, propanol) nwere a ísì mmanya, ọkara (isopropanol, butanol, isobutanol, pentanol, hexanol) - fusel mmanụ, elu - dịghị ísì ụtọ. Alcohols nwere nnukwu mmiri ịgbọ agbọ ebe, nke a na-ejikọta ya na mkpakọrịta nke ụmụ irighiri site hydrogen agbụ. Ọtụtụ n'ime ndị a na ndị ọzọ na physico-chemical Njirimara nke alcohols dịgasị na-amụba molekụla arọ.

Ọ ga-gaa na akaụntụ eziokwu na ntughari mmanya si na mmiri mmiri ka gaseous ala (na esi) etịbede na hydrogen nkekọ. The ultraviolet absorption ụdịdị dị iche iche e nwere a gbalaga na mpaghara 150-200 nm. X-ray na elektrọn diffraction omume ịchọpụta na n'akuku nke adịghị n'ahịrị njikọ C-C-N of 110 Celsius 25 '. Ma ihe ndị aromatic alcohols, mgbe ahụ, ha na-ji otu Njirimara dị ka nke acyclic alcohols. A ogige bụ ka ogbonye ma ọ bụghị soluble na mmiri, ezi - na organic solvents. Esi ebe budata elu karịa ndị kwekọrọ ekwekọ arene. The absorption gbalaga na ultraviolet na infrared spektra yiri aliphatic alcohols.

Chemical Njirimara nke aromatic alcohols

A ogige nwere otu chemical Njirimara dị ka aliphatic alcohols. Ha na-etolite alkoxides, ethers na esters, halogenated n'akụkụ yinye, na mgbe ọxịdashọn - ketones, aldehydes, na aromatic asịd. Ọzọkwa, ndị a alcohols nwere ike igosipụta Njirimara arenes. Ihe atụ, ha nwere ike na-eme benzenovogo ntọala - halogenation, nitration, sulfonation, na hydrogenation, wdg

Benzyl mmanya - siri ike, dị nnọọ soluble na ethanol, agụghị oké - na mmiri, na-agbaze na 15,3 ° C, Juda na 205,8 Celsius C. Kwadebere ya alkaline hydrolysis nke benzyl chloride site omume benzaldehyde na formaldehyde na ọnụnọ nke sodium hydroxide, nke ụfọdụ mkpa mmanụ na eke balms. Eji dị ka-esi ísì ụtọ, isi mkpọchi, na mgbaze na senti ụlọ ọrụ.

Beta-phenylethyl mmanya - siri ike agbazenụ na 27 ° C na Juda na 222 ° C, soluble na ethanol. Esịne ke pink, kloovu mkpa mmanụ. Ọ na-eji dị ka aromatic umi, nke nwere isi nke Roses. Ọzọkwa, a umi-ejikarị na senti na nri ọrụ.

Cinnamic mmanya - siri ike agbazenụ na 33 ° C, ngwa ngwa soluble na ethanol. Ọ dị tumadi n'ụdị ethers na mkpa mmanụ, keisi resins, balsams. Aromatic umi na hyacinth isi na-eji na senti ụlọ ọrụ, na dị ka ngwaọrụ maka njikọ nke kasị nke odorous bekee.
