2019 Isitayela Esisha Esithengiswa Kakhulu 2, 5-Dimethoxybenzaldehyde CAS 93-02-7, CAS 102-97-6

Abasebenzi bethu bahlale benomoya “wokuthuthukiswa okuqhubekayo nokusebenza kahle”, futhi ngemikhiqizo yekhwalithi ephezulu, amanani avumayo kanye nezinsizakalo ezinhle zangemva kokuthengisa, sizama ukuzuza ukwethenjwa yiwo wonke amakhasimende ngo-2019 New Style Top Sell.2, 5-Dimethoxybenzaldehyde CAS 93-02-7, CAS 102-97-6, Singenza ngokwezifiso izimpahla ngokwezidingo zakho futhi sizokuphakela yona mathupha lapho uthola.
Abasebenzi bethu bahlale besemoyeni “wokuthuthuka okuqhubekayo nokwenza kahle”, futhi ngemikhiqizo yekhwalithi ephezulu, intengo encomekayo kanye nezinsizakalo ezinhle zangemuva kokuthengisa, sizama ukuzuza ukwethenjwa yiwo wonke amakhasimende, Ngeshabhu ethuthukisiwe, ithimba labaklami abaqeqeshiwe kanye nohlelo oluqinile lokulawula ikhwalithi, okusekelwe ekupheleni kuya ekupheleni okumakwe njengokumaketha kwethu, izimpahla zethu zingezamakethi e-Europe futhi zidayiswa ngokushesha njengama-market aseMelika aseMelika. kanye noYisilanya.

I-2,5-Dimethoxybenzaldehyde iyimpushana yekristalu ephuzi ekhanyayo enesisindo semolekyuli esingu-166.18 kanye nephoyinti elibilayo elingu-146°C. Incibilika kuzincibilikisi zemvelo njenge-ethanol ne-ether. Isetshenziswa kakhulu njengendawo ephakathi yemithi.

Ngaphezu kokuthi i-oxidized noma yehliselwe ku-2,5-dimethoxybenzoic acid, i-benzonitrile noma i-benzyl alcohol,2,5-dimethoxybenzaldehydengokwayo futhi inenani lesicelo eliyingqayizivele. Ngokusabela ngezinto ezinezinhlobo ezahlukene zamaqembu asebenzayo, ama-molecule ezidakamizwa anezakhiwo ezahlukene kanye nemiphumela ehlukene angatholakala. Isifo sikaParkinson (PD) yisifo esivamile se-neurodeergenerative, futhi izimpawu zaso eziyinhloko zomtholampilo zihlanganisa ukundindizela kwemisipha, ukuqina, ubunzima bokunyakaza, ukuma komzimba kanye nokuphazamiseka kokulingana kokunyakaza. Ukuthuthuka okuqhubekayo kuzoholela ekuqashelweni, ekuboneni, ekuphazamisekeni kwenkumbulo kanye nokuwohloka komqondo okusobala. Njengamanje, ukwelashwa kwe-PD ikakhulukazi kuhlanganisa ukwelapha izidakamizwa, ukwelashwa ngokuhlinzwa kanye nokwelashwa ngofuzo. Ekwelashweni kwezidakamizwa, i-phenamidine itholakale inomthelela omuhle ku-PD, enobuthi obuphansi nokuphepha okuhle, futhi ukuhlanganiswa kwe-phenamidine kudinga ukusetshenziswa kwe-2,5-dimethoxybenzaldehyde njengento yokuqala.

Ngokwendlela yokuhlanganisa ebikwe ezincwadini,2,5-dimethoxybenzaldehydeitholakala ikakhulukazi ngokusabela i-1,4-dimethoxybenzene nge-ejenti ye-formylation. Ama-Formylation agents ahlanganisa (1) ingxube ye-1,1-dichloromethyl ether ne-titanium tetrachloride; (2) ingxube ye-N,N-dimethylformamide ne-phosphorus oxychloride, ingxube ye-N,N-dimethylformamide ne-oxalyl chloride; (3) ingxube ye-N,N-dimethylformamide ne-thionyl chloride noma ingxube ye-urotropine ne-magnesium chloride. Nokho, lezi zindlela zidinga ukusetshenziswa kwenani elikhulu le-titanium tetrachloride, i-phosphorus oxychloride noma i-thionyl chloride. Lawa ma-reagents azinzile futhi abola kalula, futhi inani elikhulu legesi le-hydrochloric acid likhishwa ngesikhathi sokusabela, elingahambisani nemvelo futhi linezidingo eziphezulu zenqubo yokusebenza.

Kuphakanyiswe indlela entsha yokuhlanganisa. Le ndlela isebenzisa i-1,4-dimethoxybenzene kanye ne-formaldehyde njengezinto zokusetshenziswa, futhi yenza ukuhlangana kwe-photooxidative lapho kukhona umoya-mpilo kanye ne-catalyst ngaphansi kwe-irradiation yokukhanya eluhlaza okwesibhakabhaka ukuze kuhlanganiswe kahle i-2,5-dimethoxybenzaldehyde. Le ndlela isebenzisa umoya-mpilo noma umoya njenge-oxidant, ayikhiqizi igesi ene-asidi, futhi ihambisana nemvelo. Ngaphezu kwalokho, le ndlela isebenzisa i-cobalt eshibhile njenge-catalyst, ephansi ngentengo futhi ifanele ukusetshenziswa kwezimboni.
