Title: Process for the recovery of glycerol from still residues from fermentation processes
IPC: C11D19/00
Filed: 1938-03-04
Abstract: 515,831. Recovering glycerine. WALMESLEY, R. A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 4, 1938, Nos. 6904 and 8966. [Class 91] A process for recovering glycerine from still residues consists in bringing the water content of the liquor to a low value and extracting the glycerine by a liquid solvent for glycerine consisting of a volatile nitrogen base substantially immiscible with water. Such solvents are aniline, quinoline, or toluidine. The glycerine-containing liquor may be subjected to a pre-extraction with a volatile solvent for glycerine which is miscible with water, such as alcohol or pyridine, the extract being heated to remove the solvent and the product then extracted with the nitrogen base solvent. In an example, a liquor containing 50 per cent. of glycerine and 40 per cent. of non-volatile impurities, obtained by removing the alcohol from an alcohol extract of a crude fermentation glycerine still residue, is mixed with 10 times its weight of water-free aniline. The temperature is raised to 100-110‹C. to keep the water content low and the liquids allowed to cool and separate. The main aniline extract is withdrawn and the lower layer subjected to further extraction by aniline. After separation the resulting weak extract is steam-distilled to recover the aniline for use for further extractions. The main aniline extract is treated with 4 parts of water per part of glycerine and the layers allowed to separate. The water may be the weak glycerine extract left after steamdistilling off the aniline from the weak extract. The aqueous layer contains the glycerine.

Abstract: 755,657. Reciprocating pumps. STOKES, R. O. March 10, 1955 [March 10, 1954], No. 7009/54. Class 102(1). [Also in Group XXIX] A multi-throw reciprocating pump comprises spring-loaded plungers 3 actuated by eccentrics 2 on a shaft 1 ; the shaft being driven through reduction gearing from an electric motor. Each plunger reciprocates in a cylinder 5 connected by a chamber 7 and a valve 17, 19 to a pipe 8 leading to a ram. Each chamber 7 has a spring- loaded inlet valve 10 and a spring-loaded relief valve 11. The valve 17, 19 is a combined inlet and exhaust valve and is built into the pump body. When oil is to be pumped to the rams, a lever 27 is turned to lower a spring loaded tappet 23 whereby the valve 19 is opened and the valve 17 is closed. The pumped oil passes through the open valve 19 and raises the valve 17 against a loading spring. When the pump withdraws oil from the rams, the lever 27 is turned to raise the tappet and close the valve 19 whereupon a spigot 20 raises the valve 17. Oil drawn through the valve 17 opens the valve 19 against its loading spring. Specification 408,303 [Group I] is referred to.

Abstract: 1,178,438. Unwoven filamentary structures. CARL FREUDENBERG. 15 Feb., 1967 [16 Feb., 1966], No. 7296/67. Heading B5B. [Also in Division D1] A non-woven filamentary structure in the form of a fleece composed of continuous bundles of continuous filaments of organic thermoplastic polymeric material in which each bundle comprises two or more filaments substantially parallel to one another and in which the filaments may be fused to one another within each bundle may be produced by melt extruding the polymeric material through groups of apertures of a spinneret in which the apertures are arranged in one or more rows to form one or more sheets of bundles of continuous filaments, stretching the bundles by gas streams ejected from slots one on each side of the or each row of apertures and adjacent and parallel to that row, and leading the or each sheet of bundles, together with its associated gas streams, through an open ended duet through which the bundles pass substantially without turbulence, the bundles being stretched and set whilst being kept parallel to but separate from one another, and forming a fleece by collecting the sheet or sheets of bundles on a carrier. The reference to the apertures being arranged in groups is defined as meaning that the nearest points of approach of the apertures within a group is less than the distance between the nearest points of approach of adjacent groups. The apparatus used may be that described in Specification 1,055,187 modified in that the apertures in each row of apertures in the spinneret are arranged in groups. The arrangement of the apertures and the conditions of operation may be such that the filaments in each bundle fuse together before solidification to form conjugate filaments or such that the filaments in each bundle remain separated from one another. Different polymeric materials may be extruded through different apertures within a row and this may be effected in such a manner that the upper and lower surfaces of the fleece consist of filament bundles of one polymer and the central portion of the fleece consist of filament bundles of another polymer, e.g. the polymers may be a polyester in the first case and a polyamide in the second.

Title: Process for the preparation of organic sulphonates and the organic sulphonates so prepared
IPC: C07B45/02
Filed: 1949-03-18
Abstract: Organic sulphonates are prepared by the addition of a bisulphite ion to an organic compound containing one or more olefine bonds in the presence of pyridine as a mutual solvent and an organic peroxide, in which both valencies of the peroxy group are satisfied by organic radicals at least one of which is attached by a tertiary carbon atom, as a reaction initiator.  The reaction temperature is preferably between 60 and 120 DEG  C., the amount of peroxide employed is from 0.005 to 0.05 moles. per mole. of olefine, and the amount of mutual solvent 0.75 to 1.5 volumes per volume of olefine.  Suitable organic peroxides are tertiary alkyl peresters such as tertiary butyl perbenzoate, 2,2-bis-(tertiary alkyl peroxy) alkanes such as 2,2-(tertiary butyl peroxy) butane, and di-tertiary alkyl peroxides such as di-tertiary butyl peroxide.  In modifications, methanol may replace the pyridine when tertiary alkyl peresters or 2,2-bis-(tertiary alkyl peroxy) alkanes are used as initiators; and ethanol or hexanolamine may replace the pyridine when tertiary alkyl peresters are used as initiators.  Particularly useful reaction pairs are 2,2-bis-(tertiary butyl peroxy) butane with methanol or pyridine; tertiary butyl perbenzoate with methanol, ethanol hexanolamine or pyridine; and di-tertiary butyl peroxide with pyridine.  Many suitable olefines are specified.  As a source of bisulphite ions, sodium or ammonium bisulphite, sulphurous acid or gaseous sulphur dioxide may be used.  In examples, ammonium octane sulphonate is obtained by heating 1-octene and ammonium bisulphite in presence of (1) methanol and 2,2-bis-(tertiary butyl peroxy) butane; (2) methanol and tertiary butyl perbenzoate; and (3) hexanolamine and tertiary butyl perbenzoate; (4) ammonium decane sulphonate is made by heating 1-decene with ammonium bisulphite in the presence of methanol and tertiary butyl perbenzoate; (5) ammonium dodecane sulphonate is made by heating 1-dodecene with ammonium bisulphite in the presence of methanol and tertiary butyl perbenzoate; (6) ammonium tetradecane sulphonate; and (7) ammonium hexadecane sulphonate are made as in (5) but using 1-tetradecene and 1-hexadecene, respectively; and (8) sodium octane sulphonate is made as in (2) using sodium bisulphite instead of ammonium bisulphite.  The Specification as open to inspection under Sect. 91 refers also to the use of other mutual organic solvents and specifies many alcohols, cyclic ethers and organic amines.  It also refers to 2-benzoyl-peroxy-1,1-dimethyl-hexane as a reaction initiator. This subject-matter does not appear in the Specification as accepted.
