Utu Pai a te Kaihanga FORMAMIDE CAS: 75-12-7

1. Ka whakamahia te formamide hei whakangawari me te whakarewa mō te kāpia kararehe me te pepa, hei miro i ngā copolymers acrylonitrile, hei polymerization o ngā amine kore mākū, hei whakarewa i roto i te hanga rongoā, hei whakarewa mō te purenga hinu, me ngā tūemi whakarewa kua whakahuatia ake nei. Ka whakamahia hei takawaenga hei hanga i te imidazole, pyrimidine, 1,3,5-triazine, caffeine, theophylline, theobromine. Ka whakamahia hei rauemi mata mō ngā tae, ngā kakara, ngā pigments, ngā piripiri, ngā āwhina kakahu, ngā kaihoko maimoatanga pepa, me ētahi atu. He rauemi mata mō te hanga waikawa formic me te dimethylformamide, me ētahi atu.

2. Whakamahia hei rauemi mata mō te hanga i te imidazole, pyrimidine, 1,3,5-triazine, caffeine, whakarewa mō te miro o te copolymer acrylonitrile, paninga antistatic o ngā hua kirihou, me ētahi atu.

3. He kaha te tauhohenga o te Formamide, ā, he kaha motuhake ki te whakarewa, ā, ka taea te whakamahi hei rauemi mata mō te hanga matū waro, hei kaihoko tukatuka pepa, hei whakangawari mō te umanga muka, hei whakangawari mō te kāpia kararehe, hei matū tātari hoki mō te whakatau i te nui o te waikawa amino i roto i te raihi. I roto i te hanga matū waro, e whakamahia ana i roto i te rongoā, ā, he maha ngā whakamahinga i roto i ngā patupatu, ngā tae, ngā tae, ngā kakara, me ngā āwhina. He whakarewa matū waro pai rawa atu hoki, e whakamahia ana i roto i te miro o te copolymer acrylonitrile me te kapia whakawhiti katote, tae atu ki te paninga ārai-pūmau, te paninga kawe rānei o ngā hua kirihou. Hei tāpiri, e whakamahia ana hoki mō te wehewehe i te chlorosilane, te hinu purenga me ētahi atu. Ka taea e te Formamide te pā ki ngā tauhohenga rerekē. Haunga te tauhohenga matū e pā ana ki ngā hauwai e toru, ka taea hoki te pā ki te maroke, te tango-CO, te whakaurunga o ngā rōpū amino, te whakaurunga o ngā rōpū acyl me te cyclization. Hei tauira, ko te loopping te mea e cyclized ai te Diethyl malonate ki te formamide hei whiwhi i te 4,6-dihydroxypyrimidine, he takawaenga o te huaora B4. Te huringa o te waikawa anthranilic me te amide hei whiwhi i te takawaenga quinazolone-4 o te roline auau antiarrhythmic. Te huringa o te 3-amino-4-ethoxycarbonylpyrazole me te formamide hei whiwhi i te aukati xanthine oxidase allopurinol. Ka hurihia te waikawa ethylenediaminetetraacetic me te formamide hei whiwhi i te rongoā anticancer ethyleneimine. Mā te huringa o te methylethyl methoxymalonate me te formamide ka puta te disodium 5-methoxy-4,6-dihydroxypyrimidine, he takawaenga o ngā sulfonamides.

4. Whakamahia hei matū tātari, whakarewa me te whakangawari, e whakamahia ana hoki i roto i te hanga matū waro.

5. Whakamahia i roto i te umanga rongoā me te patu pepeke.
