Perm National Research Polytechnic University (PNRPU) is developing a technology for processing styrofoam. It will allow to obtain the aroma of rose and strawberry. This was reported in the press service of the university.
In the future, the fragrances are planned to be used as fragrances in cosmetics and household chemicals.
PNRPU scientists are developing a method for processing polystyrene by thermal depolymerization, in which it breaks down back to the monomer - styrene. In the process, a condensate is released, the processing of which allows you to create fragrances with various aromas.
The technology involves grinding and heat treatment of raw materials. Recycling styrofoam will reduce the burden on the environment.
We obtain a pitch fraction and a target condensate, which is distilled with steam. We select the resulting styrene fractions and process them to phenylethylene glycol and acetophenone. These molecules are the basis of rose and strawberry aromas.
Specialists continue laboratory tests. Their goal is to optimize the processing process and scale the depolymerization unit.
The technology will allow to obtain new chemical compounds. They can be used as additives for corrosion inhibitors, lubricants and as components for pharmaceutical preparations.
Earlier www1.ru reported that PNRPU scientists made bionic hand prostheses more accurate.
