BACKGROUND Butyl butyrate has been considered as a promising fuel source because it is a kind of natural ester which can be converted from renewable and sustainable lignocellulosic biomass. Compared with the conventional chemical methods for butyl butyrate production, the enzymatic approach has been demonstrated to be more attractive, mainly owing to the mild reaction conditions, high specifici...

The environmental contamination and fate of benzotriazole UV stabilizers (BZTs) have received increasing attention due to their large production volume and wide usage in various consumer and industrial products. In the present work, 60 municipal sewage sludge samples from wastewater treatment plants (WWTPs) in 33 cities in China were collected to investigate the occurrence and distribution of 9...

The title compound, C(18)H(18)Br(2)N(2), is centrosymmetric with the mid-point of the central C-C bond of the butyl group located on an inversion center. The terminal benzene ring is approximately perpendicular to the central butyl plane [dihedral angle = 71.9 (8)°]. No hydrogen bonding or aromatic stacking is observed in the crystal.

Near-infrared absorbing aza-BODIPYs with 1,7-di- tert -butyl groups (tBuazaBDP) were successfully synthesized.

Butyl rubber (polyisobutylene-co-isoprene (IIR)) is a very important commercial elastomer with many desirable physical properties, such as low air permeability and broad damping properties. The principal uses of this material are in the tire industry for the preparation of inner tubes and inner liners of passenger car tires. Despite these unique properties, there are some deficiencies associate...

Tert-butyl alcohol, an important commodity chemical, additive to unleaded gasoline, and contaminant of drinking water, was evaluated for toxicity and was found to enhance nephropathy in male Fischer 344 rats. Because male rats treated with t-butyl alcohol for 2 years had a low incidence of renal cortical tumors, additional renal sections for the 90-day toxicity study were examined for the prese...
