P&G Chemicals (PGC) is a division within Procter and Gamble that specializes in the production and distribution of oleochemicals throughout the world. [1]With a line of products including glycerine, methyl esters, alcohols, fatty alcohols, and sucrose polyesters such as Sefose and Olean, PGC produces raw materials essential for many commonly used consumer products, and is a global supplier for ...
Epoxidized soybean oil (ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics . ESBO is a yellowish viscous liquid.
Biodiesel is an effective solvent to oil due to its methyl ester component, which considerably lowers the viscosity of the crude oil. Additionally, it has a higher buoyancy than crude oil, which later aids in its removal. As a result, 80% of oil was removed from cobble and fine sand, 50% in coarse sand, and 30% in gravel.
One reason for using FAME (fatty acid methyl esters) in biodiesel production, rather than free fatty acids, is to mitigate the potential corrosion they can cause to metals of engines, production facilities, and related infrastructure. While free fatty acids are only mildly acidic, over time they can lead to cumulative corrosion.
Solae LLC (which traded as The Solae Company) was an international soy ingredients supplier based in St. Louis, Missouri. Solae was formed as a joint venture between DuPont and Bunge Limited . On May 1, 2012, Solae announced that DuPont had acquired Bunge's 28% share, thus taking full ownership of the company. [ 1 ]
The process can tolerate water in the feedstock, free fatty acids are converted to methyl esters instead of soap, so a wide variety of feedstocks can be used. Also the catalyst removal step is eliminated. [9] High temperatures and pressures are required, but energy costs of production are similar or less than catalytic production routes. [10]
The most commonly used alcohol is methanol, producing fatty acid methyl esters (FAME). When ethanol is used fatty acid ethyl esters (FAEE) are created. Other alcohols used for the production of biodiesel include butanol and isopropanol. Fatty acid ethyl esters are biomarkers for the consumption of ethanol (alcoholic beverages). [1] [2] [3]
Molten sucrose is used instead of solvent. The reaction involves molten sucrose and fatty acid ester (methyl ester or triglyceride) with a basic catalyst, potassium carbonate or potassium soap. The high temperature (170-190 °C) is required for this process. [12] Since the process is carried out at a high temperature, sucrose can be degraded.
