Barium soaps

Dispersants To keep insoluble combustion and oxidation products in suspension and dispersed Salts of phenolic derivatives polymers containing barium, sulphur and phosphorus calcium or barium soaps of petroleum sulphonic acids... 

Barium hydroxide is used to produce barium soaps which are additives for high temperature lubricants. Other chemical applications include refining of vegetable oils vulcanization of synthetic rubber in drilling fluids in corrosion inhibitors as an ingredient in sealing compositions in plastics stabilizers for softening water and to prepare other alkalies. 

Mahogany acids oil-soluble sulfonic acids formed by the action of sulfuric acid on petroleum distillates. They may be converted to their sodium soaps (mahogany soaps) and extracted from the oil with alcohol for use in the manufacture of soluble oils, rust preventives, and special greases. The calcium and barium soaps of these acids are used as detergent additives in motor oils see also Brown acids and Sulfonic acids. 

As a function of temperature, and up to 350 °C in some cases, magnesium and cadmium soaps exhibit only one or two eylindrical structures, whereas calcium soaps present both different successive struetures with disk and cylinders. These two classes of structure are found also in strontium and barium soaps, with, in addition, a body-centered cubic structure. These cubic phases have interesting features in that the polar groups are present on rods of finite length which belong to two, interwoven, infinite three-dimensional networks and the hydrocarbon chains constitute a eontinuous, paraffinic matrix (Figure 45). 

Barium hydroxide monohydrate (barium monohydrate) Ba(0H)2-H20) n. A white powder used in the production of phenol-formaldehyde resins and barium soaps. 

Alkalinity of borates is one of the important attributes of their inhibitive properties. They may also form calcium or barium soaps, depending on the pigment, with acidic functional groups in the resin. Borates act as anodic passivators, forming a protective film on metallic substrates. 

Barium Fillers n Barium sulfate or other compound of barium which serves as a filler for plastics compounding. (Ash M, Ash I (1998) Handbook of fillers, extenders and dilutents. Synapse Informtion Resources, Inc., New York) Barium Hydroxide Monohydrate n (barium monohydrate) Ba(0H)2. H20). A white powder used in the production of phenol-formaldehyde resins and barium soaps. 

A determination of methyl salicylate by isolation of the salicylic acid can be applied, eliminating fatty acids as barium soaps. The B,P.C. method is a modification ... 

Barium soaps, especially of -> 12-hydroxystearic acid, are made after method 2 b. They are used as lubricants and costabilizers in PVC (- plas-tics additives), as wetting and dispersion aids in paints and in wire drawing.
