Yog tias koj haus cawv thiab ntxiv thionyl chloride, nws yuav hloov mus rau hauv alkyl chloride. Cov byproducts ntawm no yog hydrochloric acid (HCl) thiab sulfur dioxide (SO2).
Cov tshuaj tiv thaiv ntawm thionyl chloride ntawm cawv yog dab tsi?
Mechanism of the Reaction of Alcohols with Thionyl Chloride
Thawj, a nucleophilic oxygen atom ntawm cawv displaces chloride ion los ntawm thionyl chloride los ua ib qho protonated alkyl chlorosulfite intermediate. Tom qab deprotonation ntawm qhov nruab nrab no los ntawm lub hauv paus yields alkyl chlorosulfite, ib qho inorganic ester.
Yuav ua li cas ntawm thionyl chloride ntawm ethanol yog dab tsi?
Thionyl chloride reacts nrog ethanol los tsim ethyl chloride thiab hydrogen chloride sulfur dioxide.
Yuav ua li cas thaum propanol raug kho nrog thionyl chloride?
SOCl2: Alcohols yog refluxed nrog thionyl chloride nyob rau hauv muaj pyridine los tsim thionyl chloride. Cov byproducts yog gaseous nyob rau hauv cov xwm. Yog li ntawd, lawv evaporate thiab tawm tom qab tsuas yog alkyl halides.
Yuav ua li cas rau cawv thaum kho nrog thionyl chloride thiab pyridine?
Pov thawj rau cov txheej txheem no yog raws li hauv qab no: Kev sib ntxiv ntawm pyridine rau kev sib xyaw ntawm cawv thiab thionyl chloride ua rau tsim cov alkyl halide nrog inverted configuration.
