Embodiment Construction
[0011] A kind of buffer solution hydrolysis gallic acid production process of the present invention is characterized in that: comprise the following steps:
[0012] 9) 100kg gallnuts are pulverized;
[0013] 10) Add NaH to the enamel reactor 2 PO 4 solution;
[0014] 11) Add Galla powder while stirring, and stir evenly;
[0015] 12) Slowly add H 2 SO 4 Make the pH value 1-2; add steam 0.15MPA to heat up to 120°C, control and maintain the pH of the mixture = 1-2. The reaction time is 2-4 hours, cooling and crystallization after the reaction: filtration, dehydration, decolorization, filtration, crystallization , dehydration, and drying to obtain the finished product.
[0016] This method produces gallic acid crude product yield and is 58.4%, compared with the gallic acid crude product yield of sulfuric acid process, it is 55.2%, has improved by 3.2%; 44.9%, an improvement of 3.5%.
