9.2 The Reaction of Biodiesel: Transesterification | EGEE .

The reaction typically takes place at between 40-65°C. As the reaction temperature goes higher, the rate of reaction will increase, typically 1-2 hours at 60 °C versus 2-4 hours at 40°C. If the reaction is higher than 65°C, a pressure vessel is required because methanol will boil at 65°C. It also helps to increase the methanol to oil ratio.

Biodiesel production from waste cooking oil: 1. Process .

The esterification reaction was carried out at 70 °C, 400 kPa and a 6:1 molar ratio of methanol to crude oil (Lepper and Friesenhagen, 1986). The fresh methanol stream 101 (128 kg/h), the recycled methanol stream 1111 (188 kg/h) and the H 2 SO 4 stream 103 (10 kg/h) were mixed before being pumped into esterification reactor R-100 by pump P-101.

esterification - alcohols and carboxylic acids

The esterification reaction is both slow and reversible. The equation for the reaction between an acid RCOOH and an alcohol R'OH (where R and R' can be the same or different) is: So, for example, if you were making ethyl ethanoate from ethanoic acid and ethanol, the equation would be:

Chemical profile: Europe plastisizers | ICIS

After esterification, excess alcohol is removed and the plasticizer is filtered. This is typically done in a batch reactor. DOTP is produced by reacting 2-EH with either dimethyl terephthalate or terephthalic acid at elevated temperatures and pressures, with the reaction time twice as long as DINP or DOTP.

How To Make Biodiesel With Sulfuric Acid - Utah Biodiesel .

Sep 07, 2011 · How To Make Biodiesel With Sulfuric Acid – by Norm McFarling, Nebraska BioPro AE (acid esterification) of WVO (Waste Vegetable Oil) is a way of reducing the FFA (Free Fatty Acid) content to a level that produces more biodiesel and less byproduct.

organic chemistry - Why do esters have to be distilled .

begingroup Thanks :) The esterification with these specific reagents I decided on myself, as I thought the typical acetic acid + ethanol one was quite an overdone one. The advantage of my one is that if I were to distill the crude ester, there is a ~24C difference in boiling points between ester and alcohol, whereas the aforementioned .
