Synthesis, biological evaluation of 1,3,4-oxadiazole, triazole and uracil derivatives from poly (ethylene terephthalate) waste

POLY(ethylene terephthalate) (PET) was hydrolyzed in aqueous NaOH using solar energy. PET is used as versatile reagent for the synthesis of a variety of heterocyclic compounds. Uracil (6a, b), 1,3,4-oxadiazole (9, 12a, b), 1,3,4-triazole (10, 14), thiadiazole (11a, b and 15) derivatives were synthesized from PET. The antimicrobial and antioxidant activities of the synthesized compounds were evaluated and showed significant activities.

Ionic liquids as solvent for efficient esterification of carboxylic acids with alkyl halides

The selective esterification of carboxylic acid derivatives with a variety of alkyl halides was carried out using ionic liquid as solvent in the presence of triethylamine. The reaction was found to proceed under relatively mild conditions with excellent conversions (up to 99%) and selectivities. The ionic liquid was recycled and reused. TUeBITAK.

Preparation of monoalkyl terephthalates: An overview

Terephthalic acid can be readily converted to the corresponding monoalkyl terephthalate in high yield, via a two-step procedure. This method is advantageously compared to the more representative methods described in the literature. The purification of the expected monoester, a crucial problem for this synthetic pathway, is discussed, and an original procedure has been developed. Copyright Taylor & Francis Group, LLC.

PREPARATION AND PROPERTIES OF OLIGOMERS OF DEFINED CHAIN LENGTH AND STRUCTURE AS MODELS FOR TECHNICAL COPOLYMERS

Oligomeric segments of the macromolecules with defined structure have been prepared in an attempt to answer the question whether the thermal and mechanical properties of the elastomers (polyester) are mainly influenced by the segregation or by the structu
