Commonly in liquid form and available in various chemical compositions, solvents are substances that dissolve solutes to form solutions. The amount and type of solute that a solvent can dissolve is dependent upon temperature and polarity.
1-Butanol is an industrial solvent that can be obtained either from petroleum feedstock or by biomass fermentation. Some of its characteristic properties include high energy content low vapor pressure and a better capability to combine with gasoline. Synthesis of di-n-butyl ether (DBE) in a fixed-bed flow reactor via dehydration of 1-butanol in the presence of³-alumina zeolites and Amberlyst ion-exchange resins has been investigated. Its thermophysical properties have been calculated. formation of fatty acid butyl esters (fABE) via transesterification of rapeseed and jatropha oil with 1-butanol in the presence of acid catalyst has been studied under varying conditions.

Pyridine (Pyr) is a nitrogen containing six membered heterocyclic compound commonly used as a base. It is a colorless liquid with a fishy odor. Pyridine moiety is present as a major component in a number of compounds like pyridine nucleotides pyridine alkaloids pyridine-based polymers and pyridine-containing macrocycles. It has wide application as a solvent catalyst and as an intermediate for synthesis. IR Raman and UV spectra of pyridine has been analyzed and the values obtained were used to calculate its thermodynamic properties. Photodegradation and bacterial degradation of Pyr has been studied.
