Iholeyili 2, 5-Dimethoxybenzaldehyde eRaw Powder CAS 93-02-7
Ukuza kuthi ga ngoku, sinezona zixhobo ziphuhliswe kakhulu, iinjineli kunye nabasebenzi abanamava nabaqeqeshiweyo, sithathela ingqalelo iinkqubo zokuphatha ezikumgangatho ophezulu kunye neqela elinobuhlobo elifumana ingeniso phambi/ngemva kokuthengisa inkxaso yeWholesale 2, 5-Dimethoxybenzaldehyde Raw Powder CAS 93-02-7, Siqinisekile ukuvelisa impumelelo elungileyo ngelixa kwixesha elizayo. Besizingela ukuba ngomnye wababoneleli bakho abaxhomekeke kuwe.
Ukuza kuthi ga ngoku sinezona zixhobo ziphuhliswe kakhulu, iinjineli ezinamava naqeqeshelwe umsebenzi kunye nabasebenzi, sithathela ingqalelo iinkqubo zokuphatha ezikumgangatho ophezulu kunye neqela elinobuhlobo elinobungane nenkxaso yangaphambili/emva kokuthengisa.2 5-Dimethoxybenzaldehyde kunye ne-2 5-Dimethoxybenzald, sixhomekeke kwiinzuzo zethu ukwakha indlela yorhwebo oluyinzuzo efanayo kunye namaqabane ethu entsebenziswano. Ngenxa yoko, sifumene uthungelwano lwentengiso yehlabathi lonke olufikelela kuMbindi Mpuma, eTurkey, eMalaysia naseVietnam.
I-2,5-i-Dimethoxybenzaldehyde yi-crystalline powder ekhanyayo kunye ne-molecular weight ye-166.18 kunye neqondo lokubilisa le-146 ° C. Iyanyibilika kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-ether. Isetyenziswa ikakhulu njenge pharmaceutical intermediate.

Ukongeza kwi-oxidized okanye ukunciphisa i-2,5-dimethoxybenzoic acid, i-benzonitrile okanye i-benzyl alcohol, i-2,5-dimethoxybenzaldehyde ngokwayo nayo inexabiso elilodwa lesicelo. Ngokuphendula ngezinto ezineentlobo ezahlukeneyo zamaqela asebenzayo, iimolekyuli zamachiza ezinezakhiwo ezahlukeneyo kunye nemiphumo eyahlukeneyo inokufumaneka. Isifo sikaParkinson (PD) sisifo esiqhelekileyo se-neurodeergenerative, kwaye iimpawu zaso eziphambili zeklinikhi ziquka ukungcangcazela kwemisipha, ukuqina, ubunzima bokuhamba, ukuma komzimba kunye nokuphazamiseka kokuhamba kakuhle. Uphuhliso olongezelelweyo luya kukhokelela ekuqaphelisweni, ukuqonda, ukuphazamiseka kwememori kunye nesifo sengqondo esixhalabisayo. Okwangoku, unyango lwePD ikakhulu lubandakanya unyango lweziyobisi, unyango lotyando kunye nonyango lwemfuza. Kunyango lweziyobisi, i-phenamidine ifunyenwe ibe nefuthe elihle kwi-PD, enetyhefu ephantsi kunye nokhuseleko oluhle, kwaye i-synthesis ye-phenamidine idinga ukusetyenziswa kwe-2,5-dimethoxybenzaldehyde njengento yokuqala.
Ngokwendlela yokudibanisa echazwe kwiincwadi, i-2,5-dimethoxybenzaldehyde ifunyenwe ngokuyiphendulela i-1,4-dimethoxybenzene kunye ne-agent ye-formylation. I-Formylation agents ziquka (1) umxube we-1,1-dichloromethyl ether kunye ne-titanium tetrachloride; (2) umxube we-N, N-dimethylformamide kunye ne-phosphorus oxychloride, umxube we-N, N-dimethylformamide kunye ne-oxalyl chloride; (3) umxube we-N, N-dimethylformamide kunye ne-thionyl chloride okanye umxube we-urotropine kunye ne-magnesium chloride. Nangona kunjalo, ezi ndlela zifuna ukusetyenziswa kwesixa esikhulu se-titanium tetrachloride, i-phosphorus oxychloride okanye i-thionyl chloride. Ezi reagents aziqinisekanga kwaye zibole ngokulula, kwaye isixa esikhulu segesi ye-hydrochloric acid ikhutshwa ngexesha lokuphendula, elingenabume bendalo kwaye lineemfuno eziphezulu zenkqubo yokusebenza.
Kuye kwacetywa indlela entsha yokudibanisa. Le ndlela isebenzisa i-1,4-dimethoxybenzene kunye ne-formaldehyde njengezinto eziluhlaza, kwaye yenza i-photooxidative coupling reaction phambi kwe-oksijini kunye ne-catalyst phantsi kwe-irradiation yokukhanya okuluhlaza okwesibhakabhaka ukwenza ngokufanelekileyo i-2,5-dimethoxybenzaldehyde. Le ndlela isebenzisa ioksijini okanye umoya njenge-oxidant, ayivelisi igesi eneasidi, kwaye ihambelana nokusingqongileyo. Ukongeza, le ndlela isebenzisa i-cobalt encinci njenge-catalyst, ephantsi kwexabiso kwaye ifanele ukusetyenziswa kwezoshishino.
