Alkyd resins are produced by reaction of a polybasic acid, such as phthaUc or maleic anhydride, with a polyhydric alcohol, such as glycerol, pentaerythritol, or glycol, in the presence of an oil or fatty acid. The resulting polymeric material can be further modified with other polymers and chemicals such as acryhcs, siUcones, and natural oils. On account of the broad selection of various polybasic acids, polyhydric alcohols, oils and fatty acids, and other modifying ingredients, many different types of alkyd resins can be produced that have a wide range of coating properties (see Alkyd resins). [Pg.541]

Neoprene, which is basically polychloroprene, has better resistance to heat than does natural rubber (up to 105°C), and has better resistance to mineral and vegetable oils and fatty acids. It is attacked by aromatic and... [Pg.122]

Biologically degradable rubbers can be produced from relatively cheap renewable resources such as vegetable oils and fatty acids. Due to the abundance in fatty acid compositions, many different biorubbers can be manufactured, having their own specific properties. Based on these types of rubber, several commercially interesting applications, e.g. consumables, are now being developed. [Pg.283]

This chapter shows that the solubility of C60 and C70 fullerenes can be predicted from the solubility parameter of these two molecules and the calculated solubility parameters of fatty acids and their esters. Furthermore, the solubility of C60 and C70 fullerenes in a series of vegetable oils and fatty acid esters will be presented and discussed. [Pg.319]

Commercial lecithin is soluble in mineral oils and fatty acids but is practically insoluble in cold vegetable and animal oils. Il is insoluble... [Pg.926]

We have demonstrated that vegetable oils and fatty acid esters can be selectively hardened in liquid, near-critical, or supercritical C02 or propane and in mixtures thereof at temperatures between 60 °C and 120 °C and at a total pressure up to 20.0 MPa. Table 14.2 summarizes the results for the selective hydrogenation of vegetable oils in supercritical C02 in comparison with hydrogenation reactions performed in a discontinuous (i.e., batch or semibatch) stirred-tank reactor and in a continuous trickle-bed reactor. [Pg.231]

Stable aqueous emulsions were prepared consisting of vegetable oils and fatty acids, nonionic surfactants and deionized water, and prehomogenized with the Fisher Sonic Dismembrator and completed with the Silverson Flomogenizer (emulsifier turbine). [Pg.103]

Plant oils or their derived fatty acids are inexpensive renewable carbon sources. In addition, the theoretical yield coefficient of bioproducts (PHA) from plant oil and fatty acid is considerably higher than that from sugars. High cell density fed-batch cultures produced value-added products from soybean oil or oleic acid as the carbon source. PHAs with high yield were produced by fed-batch culture of R. eutropha or its recombinant strain from soybean oil. High cell concentrations obtained by fed-batch cultures from oleic acid improved lipase activity by C. cylindracea and 10-KSA by Flavobacterium, sp. DS5, compared with those of flask cultures. There are still many industrially important value-added products that can be produced from inexpensive substrates such as soybean oil. [Pg.553]

Commercial lecithin is produced by water degumming (precipitation from oil with ion-exchange treated water), separation by stacked disk centrifuge, and vacuum drying to less than 1 percent moisture content. Crude lecithins contain 70-72 percent acetone insolubles (AI) and are standardized to 62-64 percent and an acid value of 30 by addition of oil and fatty acids before sale. Crude lecithins may be treated with acetone to obtain free-flowing powders with 95-98 percent AI. Lecithin can be additionally purified, bleached, fractionated, hydrogenated, hydrox-ylated, acetylated, sulfonated, and halo-genated.104 One domestic company makes 13 kinds of lecithin for food uses alone. [Pg.1606]

Edible oils and fatty acid esters were selectively hardened in sc CO2 at temperatures between 60°C and 90°C and at a total pressure of 10.0 MPa. In order to get different degrees of hardening, we investigated activated carbon and different DELOXAN supported precious metal fixed bed catalysts at space velocities (LHSV) between 5 and 60 h1. [Pg.19]

Prevents oxidation of sulphonated oils and fatty acids. [Pg.176]

Composition of fatty acids. The saturated and unsaturated fatty acids with 8 to 24 carbon atoms in animal fats, vegetable oils, marine oils, and fatty acids are quantitatively determined by gas chromatography (GC) after conversion to their methyl ester forms. However, free fatty acid analysis is also possible by using specially selected stationary solid... [Pg.119]

The raw material for CLA production must be a material that is rich in linoleic acid. This product could be in the triacylglycerol form, fatty acids or fatty acid esters. The concentration of CLA in the final product is directly dependent on the level of linoleic acid in the starting material. The highest level of linoleic acid available from botanical sources is not available in commercial products. Extraction and refining equipment would be required to obtain oils with the highest linoleic acid levels. Table 1 lists the commercial and noncommercial sources of oil and fatty acids that are known to be rich in linoleic acid and their availability as TAGs and fatty acids. [Pg.1374]
