Ko te 3-Chloro-2-hydroxybenzaldehyde CAS 1927-94-2 no nga pärönaki benzene ka taea te whakamahi hei takawaenga mo te whakahiato rongoa me te matū.
Shandong Whakapono
Tikanga Whakaritenga: MgCl2 (22.2g, 233.35mmol) me te triethylamine (59.03g, 583.39mmol) i whakauruhia ki te acetonitrile (200ml) whakaohooho o te 2-chlorophenol (20.0g, 155.60mmol) i te pāmahana rūma. Tāpirihia te poly (pukapuka matū formaldehyde, 0.52g, 1.05mol) ki te ranunga, kātahi ka reflux mo te 4 haora. Ko te ranunga hua ka whakamatao ki te pāmahana rūma, ka tineia ki te 2nhcl, ka tangohia ki te ether, ka whakamaroke ki te MgSO4, ka tātarihia, ka kuhu ki raro i te pehanga iti. I purea e te chromatography tīwae silica gel kia whiwhi i te pūhui taitara 3-chloro-2-hydroxybenzene.
