Contribution of yeasts to the sensory attributes of fermented foods and beverages goes far beyond sugar consumption and ethanol and carbon dioxide production. It includes some major by-products of fermentation, like glycerol or acetic acid, and hundreds of aroma-active compounds, including higher alcohols, esters, aldehydes, organic acids, volatile fatty acids or carbonyl compounds, as main con...

A facile catalytic one-pot synthesis of N-acylhydrazones via acceptorless dehydrogenative coupling readily available alcohols and benzohydrazides (R2CONHNH2) using arene ruthenium (II) complexes has been described. The with various catalysts provide a wide range in good to excellent yields (63–93%; 32 examples). present protocol offers high selectivity hydrazones without any alkylated products ...

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

In view of the rising global problems of environment pollution and degradation, the present process provides a 'green solution' to the synthesis of higher esters of lubricant range, more specifically in the range C12-C36, using different combinations of acids and alcohols, in a single step reaction. The esters produced are biodegradable in nature and have a plethora of uses, such as in additive...
