Benzyl Joala: Properties, itokisa, kopo

Nkhang hamonate alcohols - benzene homologues derivatives, ka khōlō eo athomo hydrogen e nkeloa sebaka ke hydroxy. Ha jwale, indasteri ea litlolo tse nkhang hamonate e hangata haholo sebediswa benzyl joala. Tsela eo ba komponeng emeloang ke masalla khōlō tsa joala le benzene (phenyl) - S6N5SN2ON. alcohols nkhang hamonate tšoauoa isomerism khōlō lehlakoreng ketane le placement sehlopha - OH ka ketane hydrocarbon. Joala bo ka boholo ba maemong a mang, ba fuoa lebitso la hase ea bohlokoa.

Benzyl joala: litsela tsa ho

alcohols nkhang hamonate ka boemo mahala e abuoeng ka ho tlhaho. E le busa, ba ile ba ba hlokometse ka oli e ea bohlokoa. Benzyl joala ile tsa maiketsetso tloha halogenated homologues benzene, eo ho eona halogen e localized ka ketane lehlakoreng. alcohols tsena fapana phenols tse ka holimo kaofela hobane ha baa ka ba phatlalatsa thepa asiti. Benzyl joala ho boetse ho fumaneha thepa tsa tlhaho e tala, eo e na le esters. Ka mor'a moo, ka hona, o ile a fumana e ile ntšitsoeng ka alcohols nkhang hamonate. alcohols nkhang hamonate li haufi haholo le alcohols aliphatic: ke bohato ba alkoxides a alkali tšepe ho theha; ke ho kena moea, ho itšetlehile ka sebopeho, ho e sokolohela aldehydes e lekanang kapa ketones; Ho bonolo ho ethers foromo le esters.

thepa ya moaho wa alcohols

Baemeli ba pele ba ho homologous series tsa alcohols acyclic - mokelikeli, 'me alcohols e phahameng --butle. Pele homologs (methanol, ethanol, propanol) ba le monko oa joala, mahareng (isopropanol, butanol, isobutanol, pentanol, hexanol) - oli fusel, e phahameng - se monko. Alcohols ba le phahameng e belang ntlha, e leng le amahanngoa le mokhatlo oa limolek'hule le ka litlamo hydrogen. Boholo ba tsona le ho ba bang thepa physico-lik'hemik'hale tsa alcohols fapana le eketseha boima ba 'mele ea limolek'hule.

E lokela ho nahana ka 'nete ea hore phetoho ea ho noa joala ho tloha mokelikeli ho boemo gaseous (ka a phehile) roba tlamo hydrogen. The mahlaseli absorption manyenyane ho na le sehlopha sa 'mino sebakeng se 150-200 NM. X-ray le elektrone diffraction khoneha ho fumana hore na angle ba e seng moleng coupling C-C-N ea 110 ° 25 '. Ha e le alcohols e nkhang hamonate, joale ba ba tšoauoa ka thepa e tšoanang le ea alcohols acyclic. metsoako tsena ke hampe kapa sa qhibilihang ka har'a ka metsi, e ntle - ka solvents manyolo. The belisoa ntlha haholo phahame ho feta arene e lekanang. The absorption sehlopha ka mahlaseli le go la la spectra tšoanang le alcohols aliphatic.

Lik'hemik'hale thepa ea alcohols nkhang hamonate

metsoako tsena na le e tšoanang thepa lik'hemik'hale e le alcohols aliphatic. Ba theha alkoxides, ethers le esters, halogenated ka ketane lehlakoreng, 'me ha ho kena moea - ketones, aldehydes, le acid nkhang hamonate. Ho feta moo, alcohols tsena e ka bontša thepa arenes. Ka mohlala, ba ka 'na ba itšoara benzenovogo khubung - halogenation, nitration, sulfonation, le hydrogenation, joalo-joalo

Benzyl joala - tiileng, qhibilihang ka har'a haholo ka ethanol, hampe - ka ea metsi, qhibiliha ka 15,3 ° C, taba ka 205,8 ° C. Lokisetsa hydrolysis lona alkaline tsa benzyl chloride ke itšoara benzaldehyde le formaldehyde ka ho ba teng ha hydroxide sodium, tsa oli tse ling tsa bohlokwa le balms tlhaho.
