  • Patent number: 4205006
    Abstract: Beef tallow is partitioned into five well defined fractions, each having its own distinctive fatty acid and glyceride composition and its own distinctive thermal characteristics, by a precise multi-step crystallization. Two of the five fractions are crystalline, one is a plastic solid and two are liquid. One of the liquid fractions accounts for 60% of the tallow and has a variety of uses in the formulation of salad oils, margarines and liquid and plastic shortenings. The composition and properties of the plastic solid fraction are very similar to those of cocoa butter and when it is mixed with cocoa butter it does not produce any significant change in thermal characteristics. In fact, an increment of one of the crystalline fractions or of one of the liquid fractions can be blended with an increment of the solid plastic fraction to make products that are compatible with cocoa butter and that have desirable thermal characteristics.

  • Patent number: 3987058
    Abstract: Sulfobenzylsilicas in which the organic moiety is bound to silica surfaces through a carbon-silicon bond are prepared by treating silica with thionyl chloride to chlorinate reactive silanol groups, reacting the product with benzyllithium and sulfonating the resulting benzylsilica. The sulfobenzylsilicas and their salts of noble metals are useful as bound stationary phases in various chromatographic procedures for the separation of a wide variety of natural product mixtures composed of closely related chemical compounds. For example, separation of methyl cis 9-octadecenoate and methyl trans 9-octadecenoate was readily achieved by gas-liquid chromatography on a modified silver sulfobenzylsilica column.
