Abstract: A PROCESS FOR REMOVING RESIDUAL AMOUNTS OF CARBON DIOXIDE FROM PURE ACETYLENE (WHICH HAS BEEN OBTAINED BY THERMAL CRACKING OF HYDROCARBONS AFTER A MAIN WASHING OF THE CRACKED GAS WITH DIETHANOLAMINE FOR REMOVAL OF THE MAJOR PORTION OF C02 AND SEPARATION OF THE OTHER COMPONENTS OF THE CRACKED GAS) WHICH COMPRISES FIRST GIVING THE PURE ACETYLENE A PRELIMINARY WASH WITH THE REGENERATED DIETHANOLAMINE SOLUTION FROM THE MAIN CO2 WASH, THEN FURTHER WASHING IT WITH A FRESH DIETHANOLAMINE SOLUTION SERVING TO REPLENISH THE WASH SOLUTION OF THE MAIN C02 WASH, COMBINING THE TWO WASH SOLUTIONS AND RESUPPLYING THEM TO THE MAIN CO2 WASH CYCLE.

Abstract: THE PRODUCTION OF 2,2-DIMETHYL1,3-PROPANEDIOLHYDROXYPIVALIC MONOESTER BY HEATING 2,2-DIMETHYL-3-HYDROXYPROPANAL (PRAPARED BY THE REACTION OF FORMALDEHYDE WITH ISOBUTYRALDEHYDE IN THE PRESENCE OF TERTIARY AMINES) IN THE PRESENCE OF AN ORGANIC SALT OF A TERTIARY AMINE. AS COMPARED WITH THE PRIOR ART METHODS, THE PROCESS ACCORDING TO THE INVENTION GIVES 2,2-DIMETHYL-1,3-PROPANEDIOLHYDROXYPIVALIC MONOESTER BY A SIMPLER AND MORE ECONIMICAL METHOD, IN HIGHER PURITY AND WITH A HIGHER YIELD WITH REFERENCE TO THE STARTING MATERIAL AND WITH A HIGHER SPACE-TIME YIELD OF PURE END PRODUCT. THE COMPOUND WHICH CAN BE PREPARED BY THE PROCESS ACCORDING TO THE INVENTION IS A MORE VALUABLE STARTING MATERIAL FOR THE PRODUCTION OF SYNTHETIC RESINS AND PLASTICIZERS.

Abstract: Separation of basic inorganic compounds from the reaction mixture obtained in the manufacture of hydroxypivalic acid neopentylglycol ester (2,2-dimethyl-1,3-propanediolhydroxypivalic monoester) by the addition of formic acid to the mixture obtained from the reaction of hydroxypivalaldehyde in the presence of basic catalysts, followed by filtration. The compound produced in the process of the invention is a valuable intermediate in the manufacture of polyesters, synthetic resins and plasticizers.

Abstract: AN IMPROVED PROCESS FOR THE PRODUCTION OF ALDEHYDES AND ALCOHOLS BY THE OXO PROCESS BY REACTION OF OLEFINICALLY UNSATURATED COMPOUNDS WITH CARBON MONOXIDE AND HYDROGEN IN THE PRESENCE OF COBALT CARBONYL COMPOUNDS AT ELEVATED TEMPERATURE AND SUPERATMOSPHERIC PRESSURE IN WHICH THE REACTANTS ARE INTRODUCED INTO THE REACTION ZONE AT HIGH SPEED. THE IMPROVEMENT CONSISTS IN INTRODUCING THE REACTANTS INTO A MIXING ZONE EXTENDING IN THE DIRECTION OF ENTRY OF THE REACTANTS, THE MIXING ZONE HAVING A DIAMETER HICH IS TWICE TO FIFTY TIMES THE MEANS DIAMETER OF THE STREAM OF REACTANTS SUPPLIED AND THE LENGTH OF THE MIXING ZONE BEING FROM THERE TO THIRTY TIMES ITS HYDRAULIC DIAMETER.
