The pressure on top of the liquid in the vacuum receiver is 20 inches of mercury, vacuum. To calculate suction surface pressure use one of the following formulas: inches of mercury x 1.133/ specific gravity = feet of liquid. pounds per square inch x 2.31/specific gravity = feet of liquid.
Oleochemicals in the broad sense are chemicals derived from natural fats and oils, irrespective of whether they are derived from animal, marine or vegetable sources. Similar chemicals may be synthesized petrochemicals but they are classified as Synthetic Chemicals and not oleochemicals.Oleochemical Products.xamples of downstream oleochemicals and derivatives are fatty amines, soaps, alkanolamides, esters, etc. Uses of Oleochemicals. Oleochemicals are used as raw materials for detergents and cosmetics. They are used in the production of plasticisers and as additives for plastics, rubber and textiles.
Olefin polymers are characterized by high crystallinity, which imparts satisfactory mechanical strength, high dielectric constants, and resistance to the action of corrosive substances (with the exception of strong oxidizing agents, for example, HNO 3.
