Benzyl Alcohol: Āhuatanga, takanga, tono

waiwaihā kakara - homologues benzene pärönaki, i roto i te tuwhena i whakakapi te ngota hauwai e hydroxy. I reira, Kei te tino maha whakamahia te ahumahi kakara benzyl waipiro. Ko te tātai o te pūhui fakafofonga'i e te toenga tuwhena o te waipiro me te benzene (phenyl) - S6N5SN2ON. waiwaihā kakara āhuatanga poinanahatanga mekameka taha me te türanga rōpū tuwhena - OH i roto i te mekameka pūwaro. Waipiro i roto i te nuinga o te wā, i homai te ingoa faufaa ore.

Benzyl waipiro: ara o whiwhi

Kei te whānui waiwaihā kakara i roto i te āhua noa tohaina i roto i te natura. Ka rite ki te tikanga, kua kitea e ratou i roto i te hinu faufaa. i synthesized Benzyl waipiro i homologues benzene halogenated, i roto i nei paetata te kōnakonako e i roto i te mekameka taha. rerekē ēnei waiwaihā i nga phenols runga ake katoa no te mea kihai i ratou i korerotia āhuatanga waikawa. Kei te whiwhi hoki Benzyl waipiro i ngā rauemi raw tūturu, e kei hākawa. I muri iho, ko te kupu whiwhi i tangohia ki te waiwaihā kakara. He tata rawa ki waiwaihā tīmeka waiwaihā kakara: i ki te mahi o alkoxides whakarewa alkali hanga; i te piti hāora, i runga i te hanganga rānei, kua tahuri ai ki te aldehydes hāngai ketones ranei; Ko reira ngāwari ki te puka ethers me hākawa.

ngā āhuatanga ōkiko o waiwaihā

Ko te māngai tuatahi o te raupapa huirua o waiwaihā acyclic - wai, me ngā waiwaihā teitei - totoka. homologs Tuatahi (mewaro, te waihā, waihā pōwaro) i te kakara o te waipiro, reo (rō waiwaihā, waihā pūwaro, isobutanol, waihā pēwaro, waihā owaro) - hinu fusel, teitei - kahore kakara. Waiwaihā i te nui wāhi e koropupu, e pā nei te ki te rōpū o te rāpoi ngota i te tikanga o here hauwai. Te nuinga o enei, me te tahi atu āhuatanga physico-matū o waiwaihā rerekē ki te whakanui ake i taimaha rāpoi.

kia tango te reira i ki pūkete te meka e te waipiro whakawhiti i wai ki te āhua haurehu waihā (i kohua) wawahi te here hauwai. Ko te absorption tūāwhiorangi hihi katinga i reira he he ropu i roto i te rohe 150-200 nm. X-ray, me te taea irahiko ttara ki te whakatau i te koki o te hononga nonlinear C-C-N o 110 ° 25 '. Ko te waiwaihā kakara, ka e āhuatanga ratou i te taua āhuatanga rite taua o waiwaihā acyclic. Ko ēnei pūhui painga ranei e kore e wairewa i roto i te wai, pai - i roto i ngā whakarewa organic. Ko te wāhi e koropupu tino teitei ake i te arene hāngai. Te ope absorption i roto i te tūāwhiorangi hihi katinga me pōkākā rite ki waiwaihā tīmeka.

āhuatanga matū o waiwaihā kakara

Enei pūhui i nga āhuatanga matū taua rite te waiwaihā tīmeka. ahua ai ratou alkoxides, ethers me hākawa, halogenated i te mekameka taha, a ka te hāora - ketones, aldehydes, me waikawa kakara. Ano, kia whakaatu enei waiwaihā āhuatanga arenes. Hei tauira, kia huru ratou karihi benzenovogo - kōnakonakotanga, nitration, sulfonation, me hydrogenation, me ētahi atu

Benzyl waipiro - totoka, rawa wairewa i ewaro, hei painga - i roto i te wai, e rewa ana i 15,3 ° C, whewhe i 205,8 ° C. Rite tona paparetanga kawakore o benzyl pūhaumāota mā te tauhohe i benzaldehyde ki formaldehyde i te aroaro o te konutai waihā, o etahi hinu faufaa me balms tūturu. Whakamahia rite kakara, kakara raka, te whakarewa i roto i te ahumahi kakara.

koero totoka i 27 ° C me whewhe i 222 ° C, wairewa i roto i te waihā - waipiro Beta-phenylethyl. Kei roto i te māwhero, rōkara hinu faufaa. whakamahia te reira rite taonga kakara, i kua te haunga o te rōhi. Hoki, e whakamahia nuitia ana te taonga i roto i te whakakakara, me te kai ahumahi.

waipiro Cinnamic - aua mea totoka i 33 ° C, ngāwari wairewa i roto i te waihā ewaro. roto te reira i te nuinga i roto i te puka o ethers i hinu faufaa, resins reka, maperi. whakamahia taonga kakara ki hakiniti kakara i roto i te ahumahi kakara, a kia rite ki rauemi mata mo te kōtuitui o te nuinga o nga matū a Whakaruru,.
