Abstract: The present invention relates to processes for obtaining Tocol products, such as tocotrienols, tocopherols and tocotrienol-like compounds from plant sources in high yields. More particularly, this invention relates to processes for stabilizing and recovering Tocol products from plant materials, such as cereals, grains and grain oils. The Tocol products recovered according to this invention are useful in pharmaceutical compositions, food formulations and dietary supplements. These compositions, formulations and supplements advantageously lower the blood level of low density lipoproteins and total serum cholesterol in humans and animals.

Abstract: An improved dispersant formulation for dispersing oil which contains a mixture of a sorbitan monoester of an aliphatic monocarboxylic acid, a polyoxyethylene adduct of a sorbitan monoester of an aliphatic monocarboxylic acid, an alkali metal salt of a dialkyl sulfosuccinate, a polyoxyethylene adduct of a sorbitan triester or a sorbitol hexaester of an aliphatic monocarboxylic acid and a solvent comprising at least one of a propylene glycol ether, ethylene glycol ether, water, alcohol, glycol, and a paraffinic hydrocarbon.

Abstract: An improved dispersant formulation for dispersing oil which contains a mixture of a sorbitan monoester of an aliphatic monocarboxylic acid, a polyoxyethylene adduct of a sorbitan monoester of an aliphatic monocarboxylic acid, a water-dispersible salt of a dialkyl sulfosuccinate, a polyoxyethylene adduct of a sorbitan triester or a sorbitol hexaester of an aliphatic monocarboxylic acid and a glycol ether which has a maximum water solubility of 25 ml/100 ml as solvent.

Abstract: A hydrocarbon solvent-based dispersant formulation which combines heavy oil penetrability, activity on oil spills on either fresh or salt water, and the density and viscosity required for controllable aerial spray application is provided by the combination of sorbitan monoesters of C.sub.10 -C.sub.20 aliphatic carboxylic acids and polyoxyalkylene adducts thereof, polyoxyalkylene adducts of sorbitan triesters of C.sub.10 -C.sub.20 aliphatic carboxylic acids, and a water-dispersible salt of a dialkyl sulfosuccinate dissolved in an isoparaffinic hydrocarbon. The addition of a viscosity modifying solvent may be advantageous for adjusting the formulation to needs of specific aerial application procedures.

Abstract: The over-pasteurization of a product in a tunnel pasteurizer can result when the normal movement of the product through the pasteurizer is delayed. Over-pasteurization is prevented by cooling the product in the pasteurizing zone to reduce its temperature to a temperature at which no appreciable pasteurization occurs. The temperature of the product may be returned to pasteurizing temperatures when the delay no longer exists. An improved tunnel pasteurizer is described for preventing over-pasteurization by spraying the product with cool water to reduce its temperature. The preferred pasteurizer also includes an automatic level control system for the regenerative paired zones, an external water tank to recover and reuse energy and water usually wasted and a closed cooling system which provides for cooling of the pasteurizer water without the risk of cross-contamination of the cooling source and the pasteurizer.

Abstract: The corrosion of ferrous metals by corrosive acids at elevated temperatures is inhibited by adding to environments containing the acids an effective amount of a novel .alpha., .OMEGA. (hereinafter "alpha", "omega", respectively) diacetylenic diol (e.g., with two acetylenic functionalities) having the structural formula: ##STR1## where R is an aliphatic, alicyclic or aromatic residue containing from 1 to about 12 carbon atoms and may include one or more functional groups such as halogen atoms, carbonyl, carboxyl, carbamyl, amino, formyl or nitroso radicals or other functional groups without impaired performance. The diacetylenic diols may be employed in combination with other corrosion inhibitors.

Abstract: Metal corrosion inhibiting compositions of outstanding utility are prepared by utilizing a selective and critical multicomponent formulation comprising in combination functionally operative proportions ofA specific quaternized cyclic nitrogen baseA specific acetylenic alcoholA surface active agentA formic acid derivative.The above formulation can be substantially improved by adding certain functionally operative additional surfactants. The choice of these surfactants is unobvious and it has been found that only a few critically selective species are operable for the purposes of the invention.

Abstract: There is described a process and apparatus for treating oleaginous seed materials, such as soybean flakes with an extraction solvent, which includes an extraction zone, a desolventizing zone, and a miscella treating zone. In the extraction zone, the oleaginous seed material is subjected to concurrent contact with a carbohydrate-selective extraction solvent in a plurality of extraction vessels arranged in countercurrent fluid relationship therebetween with the expression of treated solids being effected after each extraction. The expressed solids from the last extracting vessel are passed to a desolventizing zone wherein residual solvent is vaporized by the respective indirect and direct contact with a heat transfer medium, such as steam, to produce a protein concentrate having a concentration (moisture free basis) of proteinaceous matter of at least about 70% by weight (6.25 times the total nitrogen content by the Kjeldahl method).
