Ọrọ Iṣaaju
3- (trifluoromethyl) pyridine, ti a tun mọ ni 1- (trifluoromethyl) pyridine, jẹ ẹya-ara Organic.
Didara:
3- (trifluoromethyl) pyridine jẹ omi ti ko ni awọ pẹlu õrùn ti o lagbara. O jẹ tiotuka ni ọpọlọpọ awọn olomi Organic gẹgẹbi ethanol, dimethylformamide, ati dimethyl sulfoxide.
Lo:
3- (trifluoromethyl) pyridine jẹ lilo pupọ bi awọn ayase, awọn olomi ati awọn reagents ni iṣelọpọ Organic. O le ṣee lo bi reagent boron kiloraidi ninu iṣelọpọ ti awọn ọti, acids, ati awọn itọsẹ ester. O tun le ṣee lo bi iṣuu soda hydroxide-catalyzed borate esterification reagent fun aldehydes ati awọn ketones.
Ọna:
Awọn ọna pupọ lo wa lati mura 3- (trifluoromethyl) pyridine. Ọna ti o wọpọ ni lati gba ọja nipasẹ iṣesi ti pyridine ati trifluoromethylsulfonyl fluoride. Pyridine ti tuka sinu epo ether, lẹhinna trifluoromethylsulfonyl fluoride ti wa ni afikun laiyara ni sisọ silẹ. Awọn aati nigbagbogbo ni a ṣe ni awọn iwọn otutu kekere ati nilo isunmi to peye lati yago fun itankale awọn gaasi majele.
Alaye Aabo: O jẹ olomi ina ti o le fa ina ni rọọrun nigbati o ba farahan si ina ti o ṣii tabi iwọn otutu giga. O tun jẹ epo-ara Organic ti o le ni ipa ibinu lori awọ ara, oju, ati eto atẹgun. Awọn ibọwọ aabo, awọn gilaasi, ati awọn ohun elo mimu yẹ ki o wọ lakoko iṣẹ, ati pe iṣẹ naa yẹ ki o ṣe ni agbegbe ti o ni afẹfẹ daradara.
