Title: Photo-dyeing of textiles and similar materials
IPC: G03C1/76
Filed: 1949-12-08
Abstract: 674,642. Photo-dyeing of textiles. RAVICH, L. E. Dec. 8, 1949 [Dec. 27, 1948], No. 31508/49. Class 98 (ii). An aqueous solution of an indigosol containing a solubility promoter such as sodium lauryl sulphonate or disodium succinate and, as sensitizer, a thiocyanate, is applied to textiles such as acetate material, nylon or acrylic resin fibres, and a predetermined area is exposed to light radiation in the presence of moisture to precipitate the dyestuff thereon. Indigosols are defined as stable and soluble derivatives of vaty dyes, such as thioindigoid or anthroquinoid dyes, produced by treating the sodium salt of the leuco base thereof with chlorosulphonic acid; they are light-sensitive but are stated to require unduly long light exposure to precipitate the dyes in absence of the thiocyanate sensitizer. In an example, ammonium thiocyanate and sodium lauryl sulphonate are added to a solution of the sodium salt of the leuco compound of the dyestuff indigosol 04B (tetrabromo indigo) in water at 140‹ to 160‹F. and the material to be dyed is coated or impregnated with the resulting liquid and exposed as to a mercury vapour lamp for a few seconds to precipitate the vat dyestuff on or within the material. Exposure may be effected through a photo-plate or similar light screen to produce a pattern or design on the material and to fix the pattern it is only necessary to wash the material to remove unaffected substances. Successive sections of a material may be treated serially. The Specification as open to inspection under Sect. 91, comprises also processes of dyeing material by light exposure using indigosols alone, and those containing other sensitizers such as " cyanine," " isocyanine " and " carbocyanine." This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to carbonylation processes
Inventor: WIENER HANS BERTHOLD
IPC: C07C45/50
Filed: 1962-08-23
Abstract: Olefins are recovered in a carbonylation process for the preparation of aldehydes or alcohols from olefins in which a volatile fraction containing unreacted olefins is separated from the product, treated for the removal of alcohols, and contacted with an aqueous solution of silver fluoborate or silver fluosilicate, and thereafter recovering the olefin from the said aqueous solution; the olefin extraction step preferably involves a liquid liquid phase separation of the aqueous extraction solution in the organic volatile fraction. It is preferred to operate one or more of the steps of separation of the volatile fraction, extraction of the olefins from the volatile fraction, and recovery of olefins from the extract continuously. Non-olefinic material in the aqueous extracting solution is preferably removed therefrom before the olefins are recovered from it, for example by contacting with an immiscible organic solvent saturated with the olefin to be extracted, which olefin may be obtained from a subsequent re-generation stage.  Advantageously the organic solvent used in the purification step is paraffinic fraction differing in boiling range from the olefin.  The recovery of the olefin is preferably effected by contacting the extracting solution with an immiscible organic solvent which advantageously has a different boiling range from the olefin to be recovered by 30-40 DEG C., the paraffin being the less volatile.  The recovered olefin may be recycled to the carbonylation stage and the regenerated aqueous solution may be returned to the extraction stage.  Hydrogen peroxide may be added to the aqueous solution of silver fluoborate or silver fluosilicate containing preferably at least 600 grams of silver per litre of solution.  In the particular description the light ends resulting from the carbonylation of a mixture of C6 to C8 olefins after alcohol removal contained about 40% by weight of olefins and these were contacted at substantially atmospheric pressure and 0 DEG C. with aqueous solution of silver fluoborate in a continuous counter-current extraction system comprising three columns in series each column being equivalent to one theoretical plate.  The olefins were recovered from the silver solution by steam stripping, the silver solution having been heated to about 60 DEG  C. and the condensate from this steam stripping operation separated into two layers, the top hydrocarbon layer being separated.  In another embodiment of the invention the silver fluoborate containing the hydrocarbons is contacted counter-current with a stream of high-boiling paraffin saturated with a portion of the olefin recovered from the subsequent olefin recovery prior to actual olefin recovery.
