Yield:-
Reaction Conditions:
with hydrogenchloride;dodecatungstosilic acid in water at 20; under 760.051 Torr; for 2 h;Reagent/catalyst;
Steps:
1-3 Example 1
86 g of γ-butyrolactone was put into the flask, Keep stirring at room temperature under normal pressure. Add 5g of silicotungstic acid to the flask, Keep at room temperature and stirring at room temperature. Slowly add 200g of 20% hydrochloric acid, The reaction was stirred for 2 h. Sampling GC analysis, The γ-butyrolactone residue is less than 1%, and the γ-chlorobutyric acid content is 99% or more. The layer was allowed to stand still, and the lower layer product was collected, and the upper layer of water was repeatedly applied.
