Camphor is an organic substance obtained from camphor laurel and fir oil and used to produce diimine. These substances are used not only in medicine but also in rubber production. However, traditional methods for the synthesis of camphor diimines face a number of problems such as reaction times, low efficiency and high labor costs.
In the new method proposed by Volga State Technical University scientists, zinc 2-ethylhexanoate, an ionic liquid, is used as a catalyst. This allows you to significantly increase crop yield – up to 90%. Ionic liquids are considered more environmentally friendly than traditional solvents and catalysts because they do not contain water and are highly stable.
According to Daria Zapravdina, senior researcher at the Department of Organic Chemistry at Volgograd State Technical University, the use of ionic liquid increases the conversion of reagents by 12.5% ​​and also increases the selectivity of the synthesis. The new method greatly increases the efficiency of the process by preventing the loss of camphor due to high temperature.
