Ko a maatau utu ko te whakaheke i nga utu hoko, te roopu moni hihiri, te QC motuhake, nga wheketere pakari, nga ratonga kounga pai moLtd., Wuhan Jingkang Technology Co., Ko ta matou kamupene e whakaaro ana "nga utu whaitake, te wa whakaputa pai me te ratonga pai muri-hoko" ko ta matou kaupapa. Kei te tumanako matou ki te mahi tahi me etahi atu kaihoko mo te whakawhanaketanga me nga painga. Ka mihi atu ki nga kaihoko pea ki te whakapiri mai ki a maatau.

2,5-Dimethoxybenzaldehydehe paura tioata kowhai marama he 166.18 te taumaha ngota me te 146°C. He wairewa i roto i nga whakarewa pararopi penei i te waihano me te etera. Ka whakamahia te nuinga hei takawaenga rongoa.

I tua atu i te oxidized, te whakaheke ranei ki te waikawa 2,5-dimethoxybenzoic, benzonitrile, benzyl alcohol ranei,2,5-dimethoxybenzaldehydekei a ia ano te uara tono motuhake. Ma te tauhohenga ki nga matū me nga momo roopu mahi rereke, ka taea te whiwhi i nga ngota ngota tarukino he rereke nga hanganga me nga paanga rereke. Ko te mate o Parkinson (PD) he mate neurodegenerative noa, a ko ona tohu haumanu matua ko te wiri uaua, te uaua, te uaua o te neke, te tuunga o te tinana me nga raruraru taurite neke. Ko etahi atu whakawhanaketanga ka arahi ano ki te mohiotanga, te tirohanga, te mate mahara me te mate mate. I tenei wa, ko te nuinga o te maimoatanga o te PD ko te rongoa rongoa, te rongoa rongoa me te rongoa ira. I roto i te rongoa rongoa, i kitea he pai te paanga o te phenamidine ki te PD, he iti te paitini me te pai o te haumaru, me te whakahiato o te phenamidine me whakamahi2,5-dimethoxybenzaldehydehei rauemi timatanga.

E ai ki te tikanga whakahiato i korerotia i roto i nga tuhinga,2,5-dimethoxybenzaldehydeKo te nuinga ka whiwhi ma te tauhohe i te 1,4-dimethoxybenzene me te kaihoko hangahanga. Kei roto i nga mea whakangao (1) he ranunga o te 1,1-dichloromethyl ether me te titanium tetrachloride; (2) he ranunga o te N,N-dimethylformamide me te phosphorus oxychloride, he ranunga o te N,N-dimethylformamide me te oxalyl chloride; (3) he ranunga o te N,N-dimethylformamide me te thionyl chloride he ranunga ranei o te urotropine me te konupora chloride. Engari, ko enei tikanga me whakamahi te nui o te titanium tetrachloride, phosphorus oxychloride, thionyl chloride ranei. Ko enei reagents kaore i te pumau, ka ngawari te pakaru, ka tukuna he nui o te hau waikawa waikawa waikawa i te wa o te tauhohenga, kaore i te pai ki te taiao me te nui o nga whakaritenga mo te tukanga mahi.

Kua whakatakotoria he tikanga whakahiato hou. Ka whakamahia e tenei tikanga te 1,4-dimethoxybenzene me te formaldehyde hei rauemi mata, ka mahi i te tauhohenga honohono photooxidative i te aroaro o te hāora me te whakakōkī i raro i te irradiation marama kikorangi kia pai te synthesize 2,5-dimethoxybenzaldehyde. Ko tenei tikanga ka whakamahi i te hāora, i te hau ranei hei waikura, kaore e whakaputa i te hau waikawa, he pai ki te taiao. I tua atu, ko tenei tikanga e whakamahi ana i te cobalt iti hei whakakorikori, he iti te utu me te pai mo te tono ahumahi.
