2-Methyl-4-trifluoromethyl-thiazole-5-carboxylic acid (CAS # 117724-63-7)
Ko te 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid he pūhui waro me te tātai matū C6H4F3NO2S.
Ko te pūhui nga āhuatanga e whai ake nei:
1. Te ahua: te karaihe taekore, te paura karaihe ma ranei.
2. Ira whakarewa: mo te 70-73°C.
3. te whakarewatanga: ka whakarewahia i roto i etahi whakarewa pararopi, penei i te waiwaro, te dimethyl sulfoxide me te chloroform, he paku whakarewa ki te wai.
Ko te 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid nga whakamahinga matua ko:
1. mara ho'oraa: hei takawaenga tarukino, ka taea te whakamahi mo te whakahiato o nga momo raau taero.
2. mara pesticide: e whakamahia nuitia ana i roto i te whakahiatotanga o nga pesticides hou, te patu patupatu me etahi atu pesticides.
Ko te 2-methyl -4-(trifluoromethyl) thiazole -5-carboxylic acid te nuinga o nga tikanga e whai ake nei:
1. tauhohenga amide and formaldehyde condensation: te waikawa formic me te ethyl ester condensation ki te whakaputa waikawa anhydride, katahi me te tauhohenga tohanga amine ki te whiwhi i te hua kua whakaritea.
2. Ko te tauhohenga o te hauwai i raro i te whakangao waikawa: 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid ka tauhohehia ki te hauwai i raro i te waikawa catalysis kia whiwhi ai i te hua kua whakaritea.
Mo nga korero mo te haumaru, ko nga raraunga paitini me te haumaru o te 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid he iti noa te korero, na reira me whai waahi haumaru i te wa e mahi ana te taiwhanga, penei i te mau karaehe whakamarumaru me nga karapu, ki te whakarite kia mahia nga mahi whakamatautau i roto i te taiao hau pai. I tua atu i tera, he kino, he whakapouri pea te puhui, me tiaki kia kore e pa atu ki te kiri me te ngongo. I te wa e whakamahia ana me te rokiroki, me whai nga tikanga haumaru matū me te rongoa ki tetahi waahi maroke, whai hau me te pouri. I te wa e whakahaere ana me te tuku i tenei puhui, whai i nga ture a-rohe e tika ana me nga aratohu whakahaere haumaru. Mena kua pa atu koe ki te matū, horoi tonu ki te wai maha ka rapu awhina hauora.
