| Kupu Whakataki | benzoyl pūhaumāota (CAS98-88-4) e mohiotia ana ano he benzoyl chloride, benzoyl chloride, no tetahi momo waikawa waikawa. He wai muramura kore tae, kare ki te paoa hau. Ko nga hua ahumahi me te kowhai marama, me te kaha o te haunga kino. Ko te kohu i runga i te mucosa kanohi, te kiri me te waahanga manawa he kaha whakaihiihi, ma te whakaongaonga i te mucosa kanohi me te roimata. Ko te Benzoyl chloride he takawaenga nui mo te whakarite waikano, kakara, peroxide waro, rongoa me te kapia. Kua whakamahia ano ki te whakaahua me te hanga i nga tannins, a kua whakamahia hei hau whakaihiihi i roto i nga pakanga matū. Ko te ahua 1 te tauira hanganga o te benzoyl chloride |
| tikanga whakarite | i roto i te taiwhanga, ka taea te tiki benzoyl chloride ma te whakakore i te waikawa benzoic me te phosphorus pentachloride i raro i nga tikanga kore. Ko te tikanga whakarite ahumahi ka taea te whiwhi ma te whakamahi i te thionyl chloride me te benzaldehyde chloride. |
| kāwai mōrearea | kāwai mōrearea mō te benzoyl chloride: 8 |
| Whakamahi | Ko te benzoyl chloride he takawaenga o te oxazinone herbicide, he takawaenga ano hoki o te insecticide benzenecapid, hydrazine inhibitor. ka whakamahia te benzoyl chloride hei rauemi mata mo te whakahiato pararopi, tae me nga rongoa, me te mea he kaikokiri, dibenzoyl peroxide, tert-butyl peroxide, pesticide herbicide, me etahi atu. , Karphos) takawaenga. He mea nui ano te benzoylation me te reagent benzylation. Ko te nuinga o te benzoyl chloride e whakamahia ana ki te whakaputa i te benzoyl peroxide, ka whai i te hanga benzophenone, benzyl benzoate, benzyl cellulose me te benzamide me etahi atu mea matū matū nui, benzoyl peroxide mo te whakauru polymerization o te monomer kirihou, polyester, epoxy, whakakōkī mo te kapia kiriaku. te hanga, te whakangao-whaiaro mo nga rawa muka karaihe, te kaihoko whakawhiti mo te silicone fluororubber, te para hinu, te paraoa. te whakapouri, te whakakore i te tae o te muka, me etahi atu. Hei taapiri, ka taea te tauhohe i te waikawa benzoic ki te benzoyl chloride ki te whakaputa benzoic anhydride. Ko te whakamahinga matua o te benzoic anhydride he acylating agent, hei waahanga o te bleaching agent and flux, me te whakarite hoki i te benzoyl peroxide. whakamahia hei reagents tātari, whakamahia hoki i roto i nga mea kakara, te whakahiato waro |
| tikanga whakaputa | 1. Toluene tikanga rauemi mata toluene me te māota i roto i te marama i raro i te huru o te tauhohenga, taha mekameka chlorination ki te whakaputa α-trichlorotoluene, te whakamutunga i roto i te waikawa reo hydrolysis ki te whakaputa benzoyl pūhaumāota, me te tuku o te hauwai pūhaumāota hau (whakaputa o te wai absorption. o te hau HCl). 2. Te waikawa Benzoic me te tauhohenga phosgene. Ka makahia te waikawa benzoic ki roto i te kohua whakaahua, ka whakamahana, ka rewa, ka whakauruhia te phosgene ki te 140-150 ℃. Kei roto i te hau hiku tauhohenga hauwai pūhaumāota me phosgene unreacted, e tukinotia ki te alkali me te hau, te pāmahana i te mutunga o te tauhohenga ko -2-3 °c, a ka maturu te hua i raro i te pēhanga iti i muri i te mahi tango hau. Ko nga hua ahumahi he wai maramara kowhai. Pure ≥ 98%. Motunga kai rawa: waikawa benzoic 920kg/t, phosgene 1100kg/t, dimethylformamide 3kg/t, wai alkali (30%)900kg/t. Inaianei kua whakamahia nuitia i roto i te umanga o te waikawa benzoic me te whakarite tauhohenga benzylidene chloride. Ka taea hoki te tiki Benzoyl chloride na roto i te chlorination tika o te benzaldehyde. He maha nga tikanga whakarite. (1) Ka werahia te waikawa benzoic ka whakarewahia e te tikanga phosgene, ka whakauruhia te phosgene ki te 140 ~ 150 ℃, ka whakauruhia he nui o te phosgene kia tae ki te mutunga. Ko te phosgene ka peia e te hauota, ka uru te hau o te hiku me te whakangaro, ko te hua whakamutunga i riro mai ma te whakakore i raro i te pehanga iti. (2) ūkuikui trichloride tikanga waikawa benzoic rewa i roto i te toluene me ētahi atu whakarewa, Phosphorus trichloride i tāpiri dropwise, a ka kawea i roto i te tauhohenga mo te maha haora i muri i te maturuturunga iho, i te toluene māturu atu, a ka maturu te hua oti atu. (3) trichloromethylbenzene tikanga ki toluene taha mekameka chlorination, a ka hua hydrolysis. |
