Silica Sulphuric Acid Catalyzed Fischer Esterification Reaction under Solventless Condition: A Novel Green Chemical Reaction

Clean and Green Approach for N-formylation of Amines using Formic acid under neat reaction condition

In recent years much effort has been carried out on formylations of amines. N-formyl compounds have been widely used in organic synthesis as protecting group of amines [1]. They are also used for synthesis of pharmaceutically important heterocylces [2-5]. Formamides are the Lewis bases, which are known to catalyze reactions such as allylations [6] and hydrosilylations [7] of carbonyl compounds....

Estimation of monosaccharides by the orcinol-sulphuric acid reaction.

Imidazolium Chloride Immobilized Fly Ash as a Heterogenized Organocatalyst for Esterification Reaction under Microwave Irradiation Heating

An efficient solventless one-pot procedure for the synthesis of imidazolium-based ionic liquid under microwave irradiation is described in which 1-methylimidazole was modified by organosilane (3-chloropropyl triethoxysilane). This ionic liquid 1-methyl-3-[(triethoxysilyl)propyl]imidazolium chloride (TMICl) is immobilized on Mechanically activated Fly Ash (MFA) by co-condensation method to d...

Sulphuric Acid Adsorbed on Silica Gel. A Remarkable Acetylation Catalyst

Sulphuric acid adsorbed on silica gel is a practical and useful catalyst for acetylation of varius alcohols, Phenols and amines.

Kinetics of the Esterification Reaction between Pentanoic Acid and Methanol Catalyzed by Noncorrosive Cation Exchange Resin

The extensive demand for cleaner environment is forcing the chemical industry to use less hazardous materials. In this regard, solid catalysts have lately attracted the attention of scientists and researchers around the world.1–8 By using sufficient amounts of these heterogeneous catalysts, their catalytic activity for ester formation can be equivalent to that of conventional homogeneous cataly...
