Because of the different process of splitting decomposition, the concentration and impurities of glycerol in sweet water differ greatly with catalysts hydrolyzed at low temperature and atmospheric pressure, medium temperature and pressure, and without catalysts hydrolyzed at medium pressure and…

Natural glycerol Before 1984, glycerol was recovered from by-products of soap making from animal fat or vegetable oil.Until now, natural oils and fats are still the main raw materials for the glycerol production. About 42% natural glycerol is produced from the by-product…

The bodies of all living things have cells. However, cells cannot function properly without the presence of certain substances, such as lipids. Lipids are a group of naturally occurring molecules that include animal fats, vegetable fats, certain vitamins, triglycerides and…

Lipids are organic compounds (that is, they contain carbon, hydrogen and oxygen) that are not water-soluble, instead dissolving in fatty solvents. Three types of lipids are found in the human body and in the foods that people eat: triglycerides, phospholipids…

Glycerin, or glycerol, is a colorless and odorless syrup that tastes sweet and is a byproduct of saponification – the process of making soap – of natural fats, such as vegetable oil. You can make glycerin yourself using heat and…

Biodiesel is a promising alternative, and renewable, fuel. As its production increases, so does production of the principle co-product, crude glycerol. The effective utilization of crude glycerol will contribute to the viability of biodiesel. In this review, composition and quality…

The general composition of saponification waste liquor is about 80% water, 10% – 15% inorganic salt (NaCI), 6% – 10% glycerol, 0.1% – 1.0% fatty acid salt (Na salt), 0.1% – 0.5% NaOH. They are from nitrogenous compounds (proteins), phospholipids…

Upon first inspection, glycerol and mineral oil appear to be identical (or at least very similar) compounds: They’re both colorless, (mostly) odorless, and have mild lubricating properties that make them feel slippery when rubbed between the thumb and index finger….

Crude glycerol is the by product produced throughout the biodiesel production process. However glycerol produced at this stage is crude glycerol which is about 80% pure and contains other contaminants like methanol, water, salt and soap. Crude glycerol has approximately…

The factors affecting acid treatment are as follows. Raw oil The quality of saponification waste water depends on the quality of oils and fats. Generally, oils and fats contain protein, gum, pigment (chlorophyll, carotenoids, gossypol), resin, phospholipids, sterols, waxes and…
