Non-biodegradable plastics polymers, such as low-d. polyethylene (LDPE), polystyrene (PS), and polyvinyl chloride (PVC) are non-biodegradable and release toxic gases into the environment on combustion and after long use. This study includes the screening of a series of organic solvents for solubility parameters of LDPE and PS. The karanja biodiesel is also used as one of the solvents for the dissolution of plastics. In order to decide the best solvent to be used for the dissolution of plastic polymer, rate of dissolution, safety aspect, and cost of the solvent were considered. The solubility factor of LDPE and PS is found to be much closed to acetone, chlorobenzene, and karanja biodiesel. Out of them, karanja biodiesel is considered due to its environment friendly behavior. The output of the study is with three value-added products as high heating value fuel, good composite for low-d. cement, and an oil-adsorbent. The dissolution products obtained are chem. analyzed using FTIR and GC-MS techniques to elucidate their composition The BET and TGA techniques are used for phys. anal., viz., the porosity and thermal stability of the products resp. The findings of dissolution methods in this article are compared with the conventional pyrolysis techniques for these plastics treatment. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Formula: C20H40O2).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
