TSIKLOPENTANONUN OKSIGENAT XASSƏLI TÖRƏMƏLƏRININ SINTEZI

Abstract

The article discusses the scope of application of spiroacetals obtained by condensation of cyclopentanone and glycerol in the presence of a catalyst. Also, ethers and esters synthesized by reacting spiroacetals with tert-butyl alcohol and acetic acid chloride were tested as oxygenates of motor gasoline. For this purpose, catalytic cracking gasoline (CCG) and primary gasoline (PG) were taken, compositions were prepared with both acetal and its ethers and esters in standard ratios, and octane numbers were determined by the motor method. The results of the tests performed are presented. The industrial product cyclopentanone used as a starting material was obtained by dry distillation of adipic acid. The analysis of the obtained results shows that the octane number of 1 unit (90% CCG + 10% acetal) in the composition of spiroacetal with spiroacetal obtained from the condensation of cyclopentane with glycerol is the use of the ester of this acetal obtained with triple butyl alcohol (CCG 92.3% and 7.7% ether). increase the octane number by 2 units. In the sample prepared with the compound ester of that acetal, the octane number increased by 4 units. The comparison of the conducted tests shows that as the mass fraction of oxygen increases in compounds used as oxygenate (acetal, its simple and complex ethers), the octane number increases within a certain limit.
