Packed column for determination of pinonic acid
Packed column for determination of pinonic acid Details:

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

Using aluminum silicate, molecular sieve, graphite, diatomaceous earth, silica gel, neutral alumina, and manganese dioxide as carriers, seven supported KMnO4 (1a～1g) were prepared, and their structures were characterized by XRD. Using 1 as the oxidant, the carbon-carbon double bond of verbenone completes the oxidative cleavage reaction, and an important insecticide intermediate oligopineonic acid (2) is synthesized. Its structure is confirmed by 1H NMR and IR. The more suitable reaction conditions for Synthesis 2 are: Verbenone 13.3 mmol, 1e10.32 g (40 mmol, calculated as KMnO4), 91% AcOH 50 mL, react at room temperature for 2 h, the conversion rate is 100%, and the selectivity is 81.04% .

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.
