Patent GB-365938-A (GB)
Title: Process for the production of dry sulphonated higher alcohols
IPC: C07C303/24
Filed: 1931-05-20
Abstract: The sulphonated mixture of alcohols derived from coco nut or palm kernel oil is prepared in the form of a light, white powder, by rapidly heating the neutralized sulphonation products in a finely divided state to a temperature of about 70-90 DEG  C. and then rapidly cooling.  The products are thus simultaneously dried and purified, the hygroscopic, more volatile impurities being carried away with the water vapour.  In an example, the fatty acids derived from coco nut oil are esterified with ethyl alcohol, reduced with sodium, and after being fractionally distilled are sulphonated with chlorsulphonic acid.  The sulphonated alcohols are neutralized with soda and the resulting solution atomized in a closed chamber by means of a rotating disc.  A rising stream of heated air, moving at high velocity, meets the atomized particles, and the dry product falls to the bottom of the chamber, the stream of the solution of the sulphonated alcohols being regulated so that the temperature in the drying zone is about 70-75 DEG  C. Atomizing driers of known construction may be used.

Title: Method of bleaching textile fibers
IPC: D06L4/10
Filed: 1944-08-08
Abstract: Cellulosic goods, e.g. cotton or line, containing portions dyed with a naphthol dye, are bleached by heating the goods, damped with less than about 90 per cent (e.g. about 50-90 per cent) of their weight of an alkaline peroxide bleaching solution of a pH less than about 9.5 (preferably about 8.5-9.5), under conditions which prevent any excessive condensation of moisture on or substantial evaporation of moisture from the goods.  The damping of the goods may be effected by spraying them with the desired amount of solution, or by immersing them in the solution and then removing excess thereof by squeezing or centrifuging. The heat treatment may be effected with superheated steam or with humidified air above about 212 DEG  F., in any conventional steaming equipment, e.g. a jay shoot, which should be maintained at 212 DEG  F. or above to prevent condensation of steam on the goods.  When the goods contain motes, these may be softened by a preliminary cleaning operation, e.g. with 50-150 per cent of an alkaline solution containing a peroxide, at a moderate temperature, preferably below about 125 DEG  F.  In an example, motey gray huck towelling containing a striped centre dyed with naphthol dye is impregnated with 90 per cent of a preparatory cleaning solution of hydrogen peroxide, sodium silicate and caustic soda, laid down at room temperature overnight, washed, impregnated with a solution of hydrogen peroxide, glacial acetic acid and sodium pyrophosphate initially of pH = 8.7, passed through squeezer rolls to remove excess of solution over 70 per cent, then treated with superheated steam in a jay shoot maintained at 214 DEG  F., washed and finished. The bleaching solution may be replaced by a solution of hydrogen peroxide, sodium pyrophosphate and sodium tetraphosphate (Na6P4O13) of initial pH = 8.9, or a solution of hydrogen peroxide, sodium pyrophosphate and magnesium sulphate of initial pH = 9.0.  The hydrogen peroxide may be replaced by other peroxygen compounds, e.g. alkali or alkaline-earth metal peroxides or the perborates, persilicates or percarbonates.  Other alkaline agents specified are disodium phosphate, sodium bicarbonate and amino compounds.  The solutions may be buffered with weak acids or acid salts.
