Methanol was distilled off from the reaction mass, dichloromethane was added to the residual mass and the contents were stirred to obtain solution.

The reaction mass undergoes hydrolysis and dehydration reaction without isolation of intermediate compound in presence of aq.

HCl solution.

The reaction mass is brought to the required temperature (fixed or programmed as a function of time).

The calibration factor is determined by means of an electrical heater than emits a small amount of energy into the reaction mass.

After completion of the reaction, the reaction mass is neutralized and the product is extracted in an organic solvent which is further converted to its hydrochloride salt.

A process for adjusting polyimide polymer properties includes combining monomers in a reaction mass to form a polyimide precursor.

The water vapors evolved during the dehydration are used to separate product dianhydro sugar alcohols from the high boiling byproducts in the reaction mass.

The product is isolated from reaction mass as a salt with suitable organic acids which on further purification is converted into the free base i.e., Carvedilol.

Afterwards, the substitution of the trifluormethyl group by hydrogen is carried out by heating it in a mineral acid medium, the target product being extracted from a reaction mixture.

The reactants are brought together over a period of time to avoid an undesirable buildup of heat within the reaction mass.

When the reaction is conducted in the presence of a catalyst of SbF3, SbF5 or a mixture of SbF5 and HSO3F, the reaction mass is unexpectedly less corrosive to the reaction vessel used.

Flexible foam surfactants are designed to stabilize the reaction mass while at the same time maximizing open cell content to prevent the foam from shrinking.

This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid propellants carried on board the vehicle.

Using acceleration data from the baseplate and the reaction mass, the ground model can be used to derive particular variables for the ground model to help characterize the system.
