| titleOfInvention | Method for testing thermal stability of long carbon chain dibasic acid |
| abstract | The invention belongs to the technical field of chemical product detection, and particularly relates to a method for testing thermal stability of a long carbon chain diacid. According to the invention, the long carbon chain dibasic acid sample is subjected to anaerobic heat treatment and aerobic heat treatment, then the solution prepared is subjected to chromaticity comparison with the standard solution, and the thermal stability of the long carbon chain dibasic acid is evaluated according to the chromaticity comparison result. The method utilizes the principle that the characteristic impurities in the long carbon chain dibasic acid are yellowed under specific conditions to evaluate the thermal stability of the product, and has accurate and reliable result and good repeatability. According to the invention, the long-chain dicarboxylic acid sample is subjected to anaerobic heat treatment and aerobic heat treatment respectively, then the chromaticity comparison is carried out, the thermal stability of the long-chain dicarboxylic acid is evaluated according to the chromaticity comparison result, and the method is simple and convenient in process, simple to operate and easy to master. |
