摘要:
DESCRIBED HEREIN IS A NOVEL CLASS OF COMPOUNDS OF FORMULA
R-CH(-OH)-CH(-OH)-CH2-CH2-OH
WHERE R IS A HYDROGEN OR LINEAR ALKYL GROUP FOR FROM 1 TO ABOUT 11 CARBON ATOMS. THE COMPOUNDS ARE PREPARED BY DIHYDROXYLATION OF A 3-ALKEN-1-OL, E.G., BY PEROXIDATION IN FORMIC ACID TO THE FORMATE ESTER WHICH LATTER IS HYDROLYZED TO THE 1,3,4-TRIOL OF THE INVENTION. THE MULTIFUNCTIONAL COMPOUNDS CAN BE CONVERTED TO SURFACTANTS, EMULSIFIERS AND LUBRICANTS, AND ARE USEFUL IN THE FORMATION OF URETHANES AND ALKYD-TYPE RESINS.

1. A METHOD FOR DISPERSING FINE ANMONIUM PERCHLORATE, ALUMINUM OR FERRIC OXIDE PARTICLES OF LESS THAN 50U WEIGHT MEDIAN DIAMETER COMPRISING THE STEPS OF MIXING A SLURRY OF SAID FINE AMMONIUM PERCHLORATE, ALUMINUM OR FERRIC OXIDE PARTICLES, AN ORGANIC LIQUID AND A SURFACTANT, SAID SURFACTANT BEING OF ABOUT 0.1 TO ABOUT 0.5 PERCENT BY WEIGHT ON A TOTAL SOLIDS BASIS, WHICH LOWERS THE INTERFACIAL SURFACE TENSION BETWEEN SAID FINE ANMONIUM PERCHLORATE, ALUMINUM OR FERRIC OXIDE PARTICLES AND SAID ORGANIC LIQUID, AND ALLOWING SAID SLURRY TO STAND UNTIL SAID SURFACTANT REACTS WITH SAID AMMONIUM PERCHLORATE, ALUMINUM OR FERRIC OXIDE PARTICLEES TO EFFECTIVELY DISPERSE SAID AMMONIUM PERCHLORATE, ALUMINUM OR FERRIC OXIDE PARTICLES IN SAID SLURRY SAID SURFACTANT BEING SELECTED FROM THE GROUP CONSISTING OF SODIUM SULFONATE OF MINERAL OIL, LECITHIN, AND A MIXTURE CONSISTING ESSENTIALLY OF APPROXIMATELY EQUAL PARTS BY WEIGHT OF PHOSPHATIDYL CHOLINES, ETHANOLAMINES AND INOSITOLS, AND SAID ORGANIC LIQUID BEING SELECTED FROM THE GROUP CONSISTING OF NORMAL-HEPTANE, NORMAL-HEXANE, 1,1,2-TRICHLORO-1,2,2-TRIFLUOROETHANE, 1,1,2,2-TETRACHLORO-1,2,-DIFLUOROETHANE, ETHYL ACETATE, TETRAHYDROFURAN, BENZENE, TOLUENE, HEXANE, ACETONE, AND ETHYL ALCOHOL.
摘要:
THE PREPARATION OF MECHANICALLY FROTHED POLYURETHANE FOAMS USING A COMPOSITION CONSISTING ESSENTIALLY OF A MIXTURE OF 1 TO 10 PARTS BY WEIGHT OF A COPOLYMER COMPOSED OF SIO2 UNITS AND UNITS SELECTED FROM THE GROUP CONSISTING OF (CH3)3SIO1/2 AND Q(CH3)2SIO1/2 UNITS, WHEREIN Q IS A SOLUBILIZING GROUP, AND 0.1 TO 2 PARTS BY WEIGHT OF A SILICON-GLYCOL COPOLYMER IS DISCLOSED.
摘要:
This invention relates to the manufacture of novel polymeric products which result from the polymerization of an admixture containing lactones, alkylene oxides, and an organic monohydroxyl initiator, using potassium hydroxide as the catalyst therefor.
摘要:
An ester condensation product of (1) a perfluoro-tertiary-alkyl alcohol in which the perfluoro-alkyl group has not more than 20 carbon atoms, is directly bonded to the alcoholic hydroxyl radical, and has at least one perfluoro-methyl group bonded to the tertiary carbon atom, and (2) an organic acid of not more than 18 carbon atoms with at most double bond unsaturation and selected from the group consisting of a hydrocarbon carboxylic acid, a hydrocarbon sulphonic acid, a hydrocarbon phosphonic acid, a hydrocarbon silicic acid or cyanuric acid, or a halogen substituted counterpart thereof. Illustrative uses of these esters include inert heat exchange fluids, as polymerizable monomers, textile treatment, surface active agents, and the like.
WHEREI R1 AND R2 ARE HEREINAFTER DEFINED AND R3 IS HYDROGEN OR A METAL ION AND N IS AN INTEGER HAVING A VALUE OF 1 OR 2, ARE DISCLOSED AS DEFLOCCULATING AGENTS IN AQUEOUS VEHICLES OR SYSTEMS CONTAINING FINELY DIVIDED SOLID MATERIALS SUCH AS OIL WELL DIRILLING MUDS.
摘要:
SURFACE ACTIVE ALKYLENE OXIDE ADDUCTS OF ALKYL OLIGOSACCHARIDES, AND ALKYLENE OXIDE ADDUCTS OF MIXTURES OF ALKYL OLIGOSACCHARIDES, ALKYL GLUCOSIDES AND ALKANOIS, ARE PREPARED FROM AN ALKANOL AND GLUCOSE VIA A TRANSACETALATION REACTION, FOLLOWED BY OXYALKYLATION. PREPARATION OF THESE COMPOSITIONS MAY BE CARRIED OUT BY REACTING GLUCOSE AND A LOWER ALKANOL IN THE PRESENCE OF AN ACID CATALYST TO FORM A MIXTURE OF LOWER ALKYL GLYCOSIDES AND ALKYL OLIGOSACCHARIDES WHICH ARE THEN REACTED WITH HIGHER ALKANOLS TO FORM THE DESIRED INTERMEDIATES, FOLLOWED BY INCORPORATION OF ETHYLENE AND/OR PROPYLENE OXIDES INTO THE COMPONENTS OF THE MIXTURE.
摘要:
An aqueous drilling fluid dispersant and a method of drilling wells using said drilling fluid which contains a substituted dihydroxybenzene compound as the dispersant, namely, a dihydroxybenzene compound selected from the group consisting of a 1,2-dihydroxybenzene containing as a substituent in the 4 position a nitro-, a chloro-, a formyl-, or a (2''carboxyethenyl)-group and mixtures of said compounds.
摘要:
A COMPOSITION IS DISCLOSED WHICH CONSISTS ESSENTIALLY OF A MIXTURE OF TRIMETHYLSILYL ENDBLOCKED METHYLOPOLYOXYETHYLENE SILOXANES WHICH COMPOSITION IS USEFUL IN THE PREPARATION FLEXIBLE POLYESTER BASED POLYURETHANE FORMS. USE OF THIS COMPOSITION MINIMIZES PROBLEMS OF SPLITING AND SHRINKAGE OF THE FOAMS PROMOTES UNIFORMITY OF CELL SIZE, PROMOTES COMPATIBILITY OF THE REACTANTS AND CATALYST, AND ALLOWS WIDER PROCESSING AND FORMULATION LATITUDE.
