Pharmaceutical intermediates, muchidimbu, ikemikari mbishi zvinhu kana zvigadzirwa zvemakemikari zvinoshandiswa mukugadzirwa kwemishonga synthesis. Izvo zvigadzirwa zvine zvakakosha zvivakwa zvinogadzirwa kuburikidza nemakemikari maitiro ezviviri kana anopfuura akasiyana mbishi zvinhu muzvikamu zvakakodzera. Izvi zvepakati zvakafanana asi zvakasiyana mukugadzirwa kwemakemikari, zvakadai se ethyl acetate uye n-butyl propionate, methyl methacrylate uye methyl acrylate, nezvimwewo. Haashandiswi chete kugadzira marudzi akasiyana-siyana emishonga, asiwo kugadzirisa zvinhu zvakasiyana-siyana zvemishonga, zvakadai sekugadzikana, kunyungudika, nezvimwewo. Izvi zvinoreva kuti anogona kugadzirwa mune akajairwa makemikari zvidyarwa uye, chero bedzi iwo achisangana nemamwe mazinga emhando, anogona kushandiswa mukugadzirwa kwemishonga. Zvakakosha kucherechedza kuti mishonga yepakati pemishonga inowanzo dhura, iyo inoenderana nemaitiro avo akaoma ekugadzira uye zvakasimba zvemhando zvinodiwa. Asi uku kuomarara uye hunyanzvi kunoita kuti vepakati vemishonga vatore chinzvimbo chakakosha muindasitiri yemishonga. Pamusoro pezvo, vepakati vemishonga zvakare chikamu chakakosha cheindasitiri yemishonga yeChina. Mushure memakumi emakore ebudiriro, kemikari mbishi zvinhu uye zvepakati zvinodiwa pakugadzirwa kwemishonga yeChina zvakatoenderana, uye chikamu chidiki chete chinoda kutengwa kunze kwenyika. Uyezve, nekuda kwekuwanda kwezviwanikwa zvenyika yangu uye nemitengo yakaderera yezvigadzirwa, vazhinji vepakati vakatengeswa kunze kwenyika zvakawanda, vachihwina mukurumbira wepasirese weindasitiri yemishonga yenyika yangu.
Kazhinji, vepakati vemishonga chikamu chakakosha cheiyo indasitiri yemishonga. Nemaitiro avo emakemikari akasiyana uye maitiro ekugadzira, vanopa hwaro hwakasimba hwezvinhu zvekugadzira mishonga uye vakapawo zvakakosha kuhutano hwevanhu. batsira.
