Determination of pinonic acid with glass column
Determination of pinonic acid with glass column Details:

Name: Packed column
Specification: 2m*3mm
Model: HH-Pinonic acid

: The synthesis process of β-pinene oxidation to prepare nopinene was optimized, and the influence of reaction time, reaction temperature, catalyst type and dosage, oxidant type and dosage, and solvent type on the reaction conversion rate and selectivity were discussed. The results of the study showed: 5.00 g β-pinene, 3 mL 2 mol/L H_2SO_4, reaction time 3 h, reaction temperature 21-24℃, catalyst is cetyltrimethylammonium bromide (CTAB), dosage 0.20 g, oxidant is potassium permanganate, n (potassium permanganate): n (β-pinene) is 3.2:1, solvent is acetone, under mechanical stirring conditions, the conversion rate of nopinone synthesis reaction reaches 99.5 %, the selectivity is as high as 92.2%.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. keeps pace with the times. It uses a packed column, a hydrogen flame detector, and an area normalization method to determine the purity and impurity content of pinonic acid. The column efficiency is high, the separation is good, and the results are satisfactory.
