The texture and other physical properties of soap dispersions in mineral oil, or lubricating greases, depend largely on the degree of dispersion of the soap. Calcium and aluminium soap dispersions yield in general a very short unctuous texture owing to the small size of the soap fibres in these systems. Sodium soap dispersions show a wide range of texture from a smooth to a very fibrous character, and this is related to the dimensions of the soap fibres in the dispersion.A novel method of examination of these fibres is described, and this procedure is compared with other means. Data and photographs of soap fibres are shown.The development of large fibres is discussed and the growth of fibres by orientation and overlapping of smaller fibrils is described. Evidence is adduced by micro-manipulator examination of soap and non-soap fibres in mineral oil. The effect of glycerol, present in greases manufactured from fats, is shown to be essential for the production of long fibres in ordinary practice, and this effect is ascribed mainly to the ability of oil to wet the soap in the presence of glycerol.

Obtaining cheap and high-quality dry lubricant compositions based on local raw materials for stretching wires in the technology of obtaining small-sized wires from large-diameter wires. Dry lubricant obtained on the basis of local cheese is used for processing and drawing metals prepared from the following components: sodium soap, natriy sulphate Na2SO4 - 5.0-20.0; bura Na2B4O7·10H2O - 0.1-5.0 and talc. At present, the pilot-test work was carried out at a private company "DAVR METALL" in Namangan.

Abstract This study investigated the use of glycerol–fatty acid sodium soap mixtures to delignify woody biomass as a model for utilization of crude glycerol by-product from biodiesel manufacture. Lignin-bearing glycerol was also produced. Delignification was carried out using glycerol mixed with sodium salts of laurate, stearate, oleate, or linoleate at 100–250 °C for 0.5–3 h. Oak, beech, bamboo, and rice straw were easily delignified by 20% sodium oleate dissolved in glycerol at around 150 °C for 1 h. For softwood (Japanese cedar and spruce), delignification did not occur below 200 °C. However, the lignin content decreased from 37.5% in untreated Japanese cedar to 10.6% and from 29.4% in untreated spruce to 11.2% by treatment at 250 °C. Japanese cedar was not delignified in glycerol mixtures with oleic acid or sodium acetate. It is suggested that the surfactant activity of soap assists delignification, but the alkaline action of sodium acetate was not effective. Enzymatic saccharification of delignified Japanese cedar (9.3% lignin) and oak (3.6% lignin) samples gave glucose yields of 0.55–0.67 g/g after 72 h and these yields were comparable with that from pure cellulose (0.77 g/g). Lignin dissolution also increased the calorific value of the collected glycerol fraction from 20 to 25 MJ/kg. The results suggest that a waste-free delignification method can be achieved based on the combined processes of biodiesel and bioethanol production.
