what is esterification reaction
Answers
Answer:
Esterification is the process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water; or a chemical reaction resulting in the formation of at least one ester product. Ester is obtained by an esterification reaction of an alcohol and a carboxylic acid.
Answer:
The esterification reaction for the production of biodiesel using Niobia HY-340 starting with fatty acids has been so successful that its concept is been enlarged to include a preliminary hydrolysis step in what is now known as the “hydro-esterification” process. The hydrolysis of oils and fats is a well-known process used industrially to produce fatty acids starting with oils and fats. The “hydro-esterification” process is a two-step process. First, there is a hydrolysis of the raw material that can be constituted by oils, fats, fatty acids or any mixture of them. The hydrolysis converts all triglycerides present in the raw material into fatty acids. The fatty acids are then submitted to the esterification reaction. Preliminary cost analysis showed that this process is cost effective when compared to the traditional transesterification process even when using the same raw material (high quality oils and fats). As the “hydro-esterification” process can be used with low cost raw materials, its economical advantages are obvious.
