Title: Process for dehydration of mixtures of carbon dioxide and ammonia
IPC: C01C1/00
Filed: 1937-11-30
Abstract: 487,752. Drying gases. COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES ALAIS, FROGES, ET CAMARGUE. Nov. 30, 1937, No. 33033. Convention date, Dec. 11, 1936. [Class 34 (i)] Moist mixtures of carbon dioxide and ammonia are dried by means of an organic hygroscopic liquid of low volatility such as glycerine, or glycol or non-volatile derivatives such as the polyglycols or triethanolamine. The drying liquid is maintained at a sufficiently high temperature to inhibit condensation of solid products at the pressure employed, such as carbamate or carbonate of ammonia. Any carbon dioxide and ammonia dissolved in the liquid may be driven off, such as by distillation, and the liquid may be regenerated, preferably by vacuum distillation. The mixed gases to be dried may be obtained from the distillation of ammonia carbonate solutions derived from impure gases or when produced in the preparation of urea from carbon dioxide and ammonia.

Filed: 1964-08-17
Abstract: In depilating and degrading hides and pelts, they are subjected to the action of chlorine dioxide, as by introducing gaseous chlorine dioxide into, or by generating chlorine dioxide in, an aqueous soaking medium containing them.  Depilation is preferably effected in an aqueous medium having a pH value between 3 and 6. The medium may contain a chlorine dioxide-yielding substance, e.g. an alkali metal chlorite such as sodium or potassium chlorite. Between 1 and 10% of this substance, computed on the weight of wet hides and/or pelts, may be dissolved in the aqueous medium.  This percentage may be extended up to 50% if the substance is used in the form of a paste.  The pH of the aqueous medium may be kept within the aforesaid range by the presence of glycollic, formic, acetic, lactic, or oxalic acid, primary sodium phosphate or a mineral acid-sodium acetate buffer. Chlorine dioxide degrades the natural fat by decomposing the triglyceridic fats present.  It also decomposes cross-linked collagen fibres.

Title: Process for the production of solid, purified alkyl sulphonates
Filed: 1946-11-20
Abstract: Alkyl sulphonates are obtained by cooling the saponification products of organic sulphochloride, separating off the precipitated alkali metal chloride, passing over surfaces, preferably rollers, heated to over 100 DEG  C. to concentrate the solution and evaporate unsaponifiable constituents and forming the fused alkyl sulphonate into flakes or strips by means of cooling rollers.  The unsaponifiable portion which is removed by evaporation may be condensed and put through a sulphochlorination process.  The separation of the alkali metal chloride before passing over the heated surfaces may be effected by filtration and if desired, a centrifuging step may be added to effect a preliminary separation of part of the unsaponifiable matter.  In an example, sodium chloride is separated from aqueous alkyl sulphonate by cooling and filtration, the filtrate is centrifuged, heated on rollers to cause evaporation and formed into flakes on cooling rollers.
