or [saponification with NaOH 12M (glycerol and soap

It is preferable to subject the hard coat layer to alkali saponification.

(b) saponification with NaOH 12M (glycerol and soap):

Sodium hydroxide is added for saponification of the fatty acids to form soap.

The extract is produced by saponifing Faeces Bombycis, and then followed by extraction, acidification and salification.

The method involves subjecting the raw material to alkaline saponification in the presence of a hydrotope and molecular distillation of the unsaponifiable fraction in a high vacuum.

The method comprises performing an alkaline saponification of the raw material in the presence of a hydrotrope and a high-vacuum molecular distillation of the unsaponifiable fraction.

Extraction with a chemical solvent: Saponification is done with caustic soda or potash.

Subsequently, the polymer solution from which monomers have been eliminated is subjected to saponification in the presence of a catalyst, thereby yielding polyvinyl alcohol.

How many people in France are capable, these days, of saponifying a 20-tonne “vat”?

For products containing tocopherol or tocotrienol esters, it is necessary to carry out a preliminary saponification.

The invention relates to methods for the production of substituted pyrazole carboxylic acids of general formula (I). The key step is cyclization with hydrazines followed by saponification.

A mixture of higher primary aliphatic alcohols of 22 to 38 carbon atoms can be obtained by saponifying and extracting steps with organic solvents from sugar cane wax.

These processes are amenable to large scale synthesis and one process employs a method of saponifying an ester which reduces the inherent racemization of the α-carbon.

This is because the zinc reacts with the alkyd and causes saponification which allows the paint to dry but to never harden and cure.
