Umklamo Ovuselelekayo Wefekthri Yase-China 2, 5-Dimethoxybenzaldehyde CAS 93-02-7
Sigcizelela inqubekelaphambili futhi sethula izixazululo ezintsha emakethe unyaka ngamunye we-Renewable Design for China Factory Supply.2, 5-Dimethoxybenzaldehyde CAS 93-02-7,Sihlala siletha izinto zekhwalithi ephumelela kakhulu kanye nenkampani enhle kakhulu kubasebenzisi abaningi benkampani nabahwebi. Siyakwamukela ngokufudumele ukuze usithinte, masisungule ngokuhlanganyela, futhi sithuthukise amaphupho.
Sigcizelela inqubekelaphambili futhi sethula izixazululo ezintsha emakethe unyaka ngamunye2 5-Dimethoxybenzaldehyde kanye ne-93-02-7, Ukuze sifeze umgomo wethu "wokuzuzisa ikhasimende kuqala nokuhambisanayo" ngokubambisana, sisungula ithimba lonjiniyela elingochwepheshe kanye nethimba labadayisi ukuze sinikeze isevisi engcono kakhulu yokwanelisa izidingo zamakhasimende ethu. Siyakwamukela ukuthi usebenzisane nathi futhi uhlanganyele nathi. Siyisinqumo sakho esingcono kakhulu.
2,5-Dimethoxybenzaldehydei-crystalline powder ephuzi ekhanyayo enesisindo se-molecule engu-166.18 kanye nephuzu 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 inomphumela omuhle ku-PD, enobuthi obuphansi nokuphepha okuhle, futhi ukuhlanganiswa kwe-phenamidine kudinga ukusetshenziswa2,5-dimethoxybenzaldehydenjengento 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.
