At Perm National Research Polytechnic University (PNRPU), a technology for recycling styrofoam is being developed. It will allow obtaining the scent of rose and strawberry. This was reported by the university's press service.
In the future, the aromas are planned to be used as fragrances in cosmetics and household chemicals.
PNRPU scientists are developing a method for recycling polystyrene by thermal depolymerization, in which it breaks down back into a monomer - styrene. In the process, a condensate is released, the processing of which allows creating 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 into phenylethylene glycol and acetophenone. These molecules are the basis of rose and strawberry aromas.
Specialists continue laboratory tests. Their goal is to optimize the recycling process and scale up the depolymerization unit.
The technology will allow obtaining 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.
