Usage

General Description

BUTYL 2-ETHYLHEXYL PHTHALATE, also known as di-n-butyl phthalate (DBP), is a widely used industrial chemical primarily used as a plasticizer in the production of plastics and synthetic rubber. It is also used as a solvent in some cosmetic products, such as nail polishes and perfumes. However, concerns have been raised about its potential health effects, as it has been linked to reproductive toxicity and endocrine disruption in animal studies. As a result, the use of BUTYL 2-ETHYLHEXYL PHTHALATE is restricted in certain products in some regions, and there is ongoing research into its potential risks to human health.

Catalytic upcycling of PVC waste-derived phthalate esters into safe, hydrogenated plasticizers

Recycling of end-of-life polyvinyl chloride (PVC) calls for solutions to deal with the vast amounts of harmful phthalate plasticizers that have historically been incorporated in PVC. Here, we report on the upcycling of such waste-extracted phthalate esters into analogues of the much safer diisononyl 1,2-cyclohexanedicarboxylate plasticizer (DINCH), via a catalytic one-pot (trans)esterification-hydrogenation process. For most of the virgin phthalates, Ru/Al2O3 is a highly effective hydrogenation catalyst, yielding >99% ring-hydrogenated products under mild reaction conditions (0.1 mol% Ru, 80 °C, 50 bar H2). However, applying this reaction to PVC-extracted phthalates proved problematic, (1) as benzyl phthalates are hydrogenolyzed to benzoic acids that inhibit the Ru-catalyst, and (2) because impurities in the plasticizer extract (PVC, sulfur) further retard the hydrogenation. These complications were solved by coupling the hydrogenation to an in situ (trans)esterification with a higher alcohol, and by pretreating the extract with an activated carbon adsorbent. In this way, a real phthalate extract obtained from post-consumer PVC waste was eventually completely (>99%) hydrogenated to phthalate-free, cycloaliphatic plasticizers. This journal is
