Tukanga

Ka whakaputa tatouWaikawa Formicna te Methyl Formate tino matatau

hangarau. Tuatahi, ka puta te Methyl Formate mai i te CO me te Methanol me te mahi a te whakakōkī. I raro i tetahi pāmahana me te pehanga, ka whakamarohia te Methyl Formate ki te Waikawa Formic. Ko te Waikawa Waikawa Maama iti ka aro ki nga mea teitei ake hei whakatutuki i nga whakaritenga rereke-

nga kaihoko.

Ko nga whakamahinga matua e whai ake nei: (1) I te nuinga o te waa e whakamahia ana i roto i te hanga o te waikawa formic, te waikawa oxalic me te paura inihua, i whakamahia ano hoki i roto i te hanga o te dimethylformamide, me etahi atu. I whakamahia ano hoki i roto i te rongoa, te whakaputa me te ahumahi tae. ; (2) reagents, disinfectants me te mordant mo te whakatau i te ūkuikui me te arsenic;

(3) Ka whakamahia hei tiaki. Whakamahia e wha: mo te paninga kapia alkyd, plasticizer, kaha; (4) Ka whakamahia hei pahū, he rauemi waikawa-waikawa, he hinu whakahinuhinu rererangi, he taapiri taapiri. Tikanga hanga konutai formate (1) Ko te tauhohenga o te waro monoxide me te konutai waiwai wairewa i te 160~200 ℃ me te pehanga 2MPa ki te whakaputa i te konutai formate, katahi ka ma roto i te waikawa sulfuric acid hydrolysis, te distillation ki te whiwhi i te waikawa formic kua oti. Ko te whārite tauhohenga matua ko: CO+NaOH→HCOONa2HCOONa + H2SO4→ 2HCOOH + Na2SO4 (2) hei whakaputa i nga hua o te neopentylene glycol, te pentaerythritol me te trimethylol propane. [Raina ahumahi] waikawa formic, waikawa oxalic. [Taupū kounga tohutoro]
