Microporous H-ZSM-5 zeolite having good crystallinity and with the presence of Brønsted acid sites exclusively, was prepared by hydrothermal treatment of Expanded Perlite. The as-prepared H-ZSM-5 was used as heterogeneous ...

A molecularly imprinted electrochemical sensor for determination of isoamyl alcohol was successfully constructed by modifying the glassy carbon electrode (GCE) with gold nanoparticles (AuNPs) and reduced graphene oxide ...

Isoamyl acetate is one of the most important flavor compounds used in food industries because of its characteristic banana flavor. The ester is used as a flavoring compound in many foods and drinks, such as honey, butterscotch, ...

Composite ZSM-5/MCM-41 material has been obtained by hydrothermal synthesis of alkali-treated ZSM-5 zeolite prepared from Expanded Perlite. A two-step procedure that avoids the traditional dual template synthesis strategy ...

New carboxylesterase from organic-solvent-tolerant Bacillus licheniformis S-86 strain was characterized. The enzyme named as type II esterase showed an optimal activity in the temperature range 60–65 °C and pH 8.0. The ...

This method has been developed for extraction and determination of phenol in a urine sample by high performance liquid chromatography.After acid hydrolysis, the free phenol was extracted with isoamyl alcohol solvent, ...
