2019 Intengo Yenqwaba Yekhwalithi Ephezulu ye-2, 5-Dimethoxybenzaldehyde Powder enekhwalithi Enhle CAS: 93-02-7
Sicabanga lokho abathengi abakucabangayo, ukuphuthuma kokuphuthuma ukwenza okuthile ngesikhathi sokuthakasela isikhundla somthengi somgomo oyisisekelo, okuvumela ikhwalithi ephezulu kakhulu, ukuncipha kwezindleko zokucubungula, izindleko zinengqondo ngokwengeziwe, kuzuze abathengi abasha nabangaphambili ukusekelwa nokuqinisekiswa kwe-2019 Ikhwalithi Ephezulu Yentengo Yenqwaba2, 5-Dimethoxybenzaldehyde Powder enekhwalithi Enhle CAS: 93-02-7, Siyakwamukela ukuthi nakanjani ube yingxenye yethu ndawonye ukuze wenze inhlangano yakho ibe lula. Besijwayele ukuba ngabalingani bakho abakhulu uma ufuna ukuba nebhizinisi lakho elincane.
Sicabanga lokho abathengi abakucabangayo, ukuphuthuma kokuphuthuma ukwenza okuthile ngesikhathi sezithakazelo zesikhundla somthengi somgomo oyisisekelo, okuvumela ikhwalithi ephezulu kakhulu, ukunciphisa izindleko zokucubungula, izindleko zinengqondo ngokwengeziwe, kuwine abathengi abasha nabangaphambili ukwesekwa nokuqinisekiswa2 5-Dimethoxybenzaldehyde kanye ne-93-02-7, Sibheke ngabomvu ukuzwa okuvela kuwe, kungakhathaliseki ukuthi uyikhasimende elibuyayo noma elisha. Sithemba ukuthi uzothola okufunayo lapha, uma kungenjalo, sicela usithinte ngokushesha. Siyaziqhenya ngesevisi yamakhasimende esezingeni eliphezulu kanye nokusabela. Siyabonga ngebhizinisi lakho nokusekela!
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 kokukhanya okuluhlaza okwesibhakabhaka ukuze kuhlanganiswe kahle.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.
