IPC: C07C303/06
Filed: 1968-10-11
Abstract: 1,215,075. Unsaturated sulphates. INSTYTUT CIEZKIEJ SYNTEZY ORGANICZNEJ. 11 Oct., 1968 [12 Oct., 1967], No. 48204/68. Heading C2C. Unsaturated fatty alcohols, oxyethylated unsaturated fatty alcohols, partially sulphated unsaturated fatty alcohols and/or partially sulphated oxyethylated unsaturated fatty alcohols are sulphated, without substantial loss of unsaturation, by reaction with gaseous SO 3  in the presence of organic compounds containing nitrogen, especially amido compounds such as urea and its derivatives and amides such as dimethylformamide. A further oxyethylated compound may be present, e.g. condensates of ethylene oxide with itself or with alcohols, phenol, alkylphenols, saturated fatty acids or aliphatic amines. This compound will also be sulphated in the reaction. The products may be neutralized with NaOH. In examples: oleyl alcohol is sulphated in the presence of urea and an ethoxylated phenol, polyglycol 400 or ethoxylated nonylphenol; oxyethylated oleyl alcohol is partially sulphated with SO 3 , urea is then added and the sulphation continued.

Abstract: 1416947 Lining pipes TAKATA KOJYO CO Ltd 17 Oct 1973 [18 Oct 1972] 48283/73 Heading F2P A method of lining a pipe B (e.g. to repair the pipe) includes the steps of inserting in the pipe B a synthetic organic polymeric resin tube 8 having reinforcing fibres embedded therein and extending peripherally thereof and having an outside diameter less than the inside diameter of the pipe B, expanding the tube 8 while in a soft flexible condition at an elevated temperature into tight engagement 8<SP>1</SP> with the inside face of the pipe B by means of a pressurized fluid within the tube 8, and relieving the fluid pressure and cooling the tube while in engagement with the pipe. The tube 8 may be formed from a thermoplastic material, e.g. polyvinyl chloride or a polyolefin, or a thermosetting resin containing a heat sensitive curing or crosslinking agent. The tube may be reinforced by a woven web embedded therein in which the warp extends longitudinally and is of low elongation (e.g. stretch oriented polyester or polyamide or glass fibres) and the weft extends peripherally and is of high elongation (e.g. unstretched polyester or polyamide filaments or yarns). A heat sensitive adhesive may be applied to the inner surface of the pipe B and/or to the outer surface of the tube 8. The tube 8 is applied by inserting the tube 8 in collapsed condition into the pipe B, clamping the ends of the tube 8 between pipe end flanges 6 and end plates 9, 9<SP>1</SP> and expanding the tube 8 by hot pressurized air by means of heater 10 and pump 11. The method may be applied to the lining of new pipes before installation or to the repair of damaged pipes in situ as shown, e.g. underground pipes such as sewer pipes or mains for water, gas and utilities.

Abstract: Finely divided, amorphous, hydrous hydrogen aluminosilicates of sub-micron particle size are produced by treating finely divided amorphous sodium aluminosilicates of sub-micron particle size with a strong mineral acid, the acid being added to the aluminosilicate at a rate equivalent to the removal of 5% by weight per minute of the initial sodium contents, and the amount of acid added is stoichiometric to the sodium ions of the aluminosilicate.  The acid may be sulphuric, hydrochloric, or nitric, and the sodium aluminosilicate may be in the form of a slurry containing from 5 to 35% of solids, or it may be in the form of a filter cake. The concentration of the acid is at least 5N.
