Benzeneacetonitrile (CAS#140-29-4)

Benzeneacetonitrile (CAS#140-29-4)

Benzeneacetonitrile, nambala ya CAS 140-29-4, ndi yapadera pazinthu zambiri zamakina.
Kuchokera pamapangidwe amankhwala, amapangidwa ndi mphete ya benzene yolumikizidwa ndi gulu la acetonitrile. Mphete ya benzene ili ndi dongosolo lalikulu la π bond conjugation, lomwe limapangitsa kuti molekyulu ikhale yokhazikika komanso kugawa kwamtambo kwapadera kwa ma elekitironi, zomwe zimapangitsa kuti ikhale ndi kununkhira kwina. Gulu la acetonitrile limayambitsa polarity yamphamvu ndi reactivity ya gulu la cyano, zomwe zimapangitsa kuti molekyulu yonse ikhale ndi inertness ndi hydrophobicity yomwe imabweretsedwa ndi mphete ya benzene, komanso imapereka mwayi wochuluka wa kaphatikizidwe ka organic chifukwa gulu la cyano limatha kutenga nawo mbali zosiyanasiyana. za nucleophilic ndi electrophilic reactions. Nthawi zambiri amawoneka ngati amadzimadzi achikasu osawoneka bwino, ndipo mawonekedwe amadzimadziwa ndi abwino kusamutsidwa ndi kuyeretsedwa kudzera muzochita zanthawi zonse monga kulekanitsa kwamadzi ndi distillation mu labotale ndi kaphatikizidwe ka mafakitale. Pankhani ya solubility, imatha kusungunuka bwino mu zosungunulira za organic, monga etha, chloroform ndi zosungunulira zina zopanda polar kapena zofooka, pomwe kusungunuka kwamadzi kumakhala koyipa, komwe kumagwirizana kwambiri ndi polarity yama cell, komanso kumatsimikizira kusankha kwake. m'machitidwe osiyanasiyana.
Ndikofunikira kwapakatikati pakugwiritsa ntchito organic synthesis. Kutengera kapangidwe kawo, mitundu yosiyanasiyana yamankhwala imatha kuchitika kuti ipange zovuta. Mwachitsanzo, mwa hydrolysis anachita cyanogroup, asidi phenylacetic akhoza kukonzekera, amene ntchito m'munda mankhwala liphatikizidwe mankhwala osiyanasiyana, monga mbali unyolo kusinthidwa penicillin mankhwala; M'makampani opangira zonunkhira, ndiye chinthu chofunikira kwambiri pokonzekera zonunkhira zamaluwa monga maluwa ndi kakombo wakuchigwa. Kuonjezera apo, kuchepetsa kuchepa kwa cyano kungagwiritsidwenso ntchito kuti asinthe kukhala mankhwala a benzylamine, ndipo zotumphukira za benzylamine zimagwiritsidwa ntchito kwambiri popanga mankhwala ophera tizilombo ndi utoto, ndipo zimagwiritsidwa ntchito popanga mankhwala ophera tizilombo, utoto wokhala ndi mitundu yowala komanso yapamwamba. kufulumira.
Pankhani ya njira yokonzekera, acetophenone nthawi zambiri imagwiritsidwa ntchito ngati zopangira m'makampani, ndipo imakonzedwa ndi masitepe awiri a oxime ndi kutaya madzi m'thupi. Choyamba, acetophenone imakhudzidwa ndi hydroxylamine kupanga acetophenone oxime, yomwe imasandulika kukhala Benzeneacetonitrile pansi pa zochita za dehydrator, ndipo m'kati mwake, ochita kafukufuku akupitirizabe kukhathamiritsa zomwe zimachitika, kuphatikizapo kusintha kutentha ndi kulamulira kuchuluka kwa dehydrator. monga kukweza zokolola, kuchepetsa mtengo, ndikuwonetsetsa kufunikira kwa kupanga kwakukulu. Ndi luso laukadaulo wa organic synthesis, kukhathamiritsa kwa njira yophatikizira ya Benzeneacetonitrile imayang'ana kwambiri chitetezo cha chilengedwe ndi chuma cha atomiki, kuyesetsa kuchepetsa kutulutsa zinyalala, kupititsa patsogolo kugwiritsa ntchito bwino kwazinthu, kumathandizira pakukula kwamakampani opanga mankhwala, ndikuwonjezera ntchito yake. kuthekera.
