Esterification

Soaps, softeners, shoe polish or heart medications – they all consist of esters. Esters are formed in a reaction of alcohol and an acid with elimination of water – the esterification. The possible uses of ester are very diverse, which is due to the fact that the substances in nature assume a variety of manifestations: for example, as fragrances, fats or as cell membrane building blocks. They find their use in the most diverse areas, ranging from body care to medicine.

With LEWA process diaphragm pumps, as well as the NIKKISO Non-Seal canned motor pumps we offer the optimum solution for esterification.

Solutions

Esterification is a chemical reaction in which an ester forms from an acid and an alcohol with the elimination of water. These acids may be either organic, such as acetic acid, benzoic acid and citric acid or inorganic, such as sulfuric acid, nitric acid or phosphoric acid. Esters are found in a large number of molecules and can be found in fats as glycerol or fatty acids, in biodiesel as methyl esters of fatty acids, in bee wax as myricyl alcohol or as polyester, which are used as materials or plastics.

With a broad product portfolio, which includes both process diaphragm pumps and canned motor pumps, LEWA offers the optimal solution for metering the individual components in the esterification process.

Advantages of the process diaphragm pumps:

  • High load capacity
  • Pressures up to 1200 bar
  • Dry running safe: constant flow is ensured
  • Permanent membrane monitoring
  • Hermetically tight: leak-free processes and pure products

Advantages of NIKKISO Non-Seal canned motor pumps:

  • Standardized pumps as an alternative to standard rotary pumps
  • Conveyance of aggressive, dangerous, toxic or explosive media possible
  • Long lifetime
  • Unique bearing condition monitoring with additional connection to the process control system

Background

Ester – used everywhere.

In the ester production process, the chemical reaction and the distillation are combined into one process–reactive distillation. Ester can be formed by a reaction with alcohols and acids or acid derivatives. In the classical sense, ester is formed by a mixture of an alcohol and a carboxylic acid with another acid as a catalyst. The resulting reaction is known as esterification.

Esters are often present in food, biodiesel or flavorings. However, they are also found in soaps, detergents, fabric softeners, glycerin, shoe polish, PVC, surfactants, crop protection or in heart medicines, such as beta-blockers. You will also find a variety of uses as fragrances and aromatic substances.
