Title: Polyester film-forming process
IPC: C08L67/00
Filed: 1958-01-21
Abstract: Polyalkylene terephthalate film, which has as-cast thickness of greater than 30 mils. and is readily quenchable to the substantially amorphous state, is made by extruding on to a moving casting surface a molten polyalkylene terephthalate which has been made by reacting a polymethylene glycol of the formula HO.(CH2n.) OH, where n is 2-10, with a lower alkyl ester of terephthalic acid under ester interchange conditions and polymerising the resulting glycol terephthalate, the process being chacterized in that a polymeric glycol of the formula:- <FORM:0842777/IV(a)/1> where R is hydrogen, methyl or ethyl and X is 0-10, is added to the reaction mixture before substantial polymerization occurs and in such a proportion that the film forming polyester contains 2-5% of the polymeric glycol based on the weight of the polymethylene glycol in the ester.  Part of the alkyl terephthalate may be replaced by an alkyl ester of another dicarboxylic acid or the corresponding free dicarboxylic acid, e.g. isophthalic acid, bibenzoic acid, hexahyroterephthalic acid, adipic acid, sebacic acid, azelaic acid, a naphthalic acid, 2,5-dimethyl terephthalic acid or bis-p-carboxy-phenoxy-ethane. Ester interchange is preferably effected at 140 DEG -220 DEG C. and polymerization at 230 DEG -290 DEG C. and under reduced pressure.  The polyesters may be extruded at 270-315 DEG C. on to a drum maintained at 40-80 DEG C. and the resulting films may be oriented by stretching, e.g. to three times their original dimensions in two directions. In examples, mixtures of dimethyl terephthalate, ethylene glycol and diethylene glycol are reached in the presence of lithium hydride, zinc acetate dihydrate, antimony oxide and monoammonium phosphate to produce polyesters which are extruded into films. Specification 578,079 is referred to.

Patent GB-760003-A (GB)
Title: A process for the production of alkamine esters of n-monoalkyl and n-monoalkoxyalkyl amino-hydroxybenzoic acids
Filed: 1952-01-28
Abstract: A process for the production of esters of N-monoalkyl- or N-monoalkoxyalkylaminohydroxybenzoic acids with amino-alcohols fully substituted at the nitrogen atom comprises alkylating or alkoxyalkylating the nuclear amino group of an alkamine ester of an aminohydroxybenzoic acid by a known method for the introduction of an alkyl group or an alkoxyalkyl group into an amino group.  The alkylation or alkoxylation may be effected by reacting the alkamine ester with an alkyl halide or an alkoxyalkyl halide, and in the presence of an acid-binding agent, advantageously in an inert atmosphere and possibly under pressure.  Alternatively the ester is condensed with a ketone, alkoxy-ketone, aldehyde or alkoxy-aldehyde and the condensation product obtained is hydrogenated to the N-monoalkyl or N-monoalkoxyalkyl derivative of the ester.  The hydrogenation, which may be carried out simultaneously with the condensation, may be effected with hydrogen in the presence of Raney nickel or platinum dioxide.  In examples: (1) 4-amino-2-hydroxy-benzoic acid diethylaminoethyl ester and n-butyl bromide are heated together to form the diethylaminoethyl ester of 4-n-butylamino-2-hydroxy-benzoic acid.  Similarly prepared are (2) and (3), the corresponding 5-n-propylamino and 4-b -methoxyethylamino derivatives.  In further examples: (4) the diethylaminoethyl ester of 4-amino-2-hydroxy-benzoic acid is condensed with propionaldehyde and the 4-propylideneamino-2-hydroxy-benzoic acid diethylaminoethyl ester obtained is hydrogenated to the diethylaminoethyl ester of 4-n-propylamino-2-hydroxybenzoic acid; (5) the dimethylaminoethyl ester of 4 - amino - 2 - hydroxy-benzoic acid and butyraldehyde in isopropanol are reacted while shaking the mixture with hydrogen in the presence of platinium oxide, to form the dimethylaminoethyl ester of 4-n-butylamino-2-hydroxy-benzoic acid.  In a similar manner to (5) there are prepared (6) the piperidino-ethyl ester of 4-b -methoxyethylamino - 2 - hydroxybenzoic acid (and its hydrochloride and picrate); (7) and (8) the same compound as prepared in (1); (9) the same product as in (5).

Title: Improvements in or relating to solvent extraction of uranyl nitrate solutions
Inventor: SHULMAN NATHAN
IPC: C22B60/02
Filed: 1951-01-31
Abstract: 836,691. Treatment of irradiated uranium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 30, 1952 [Jan. 31, 1951], No. 2416/51. Class 39(4). An aqueous uranium nitrate solution derived from neutron-irradiated uranium is tested for suitability for organic solvent extraction by agitating a sample with the organic solvent in a vessel having a transparent wall, allowing to stand, and observing the conditions at the interface. Agitation is effected by slowly reversing and returning the vessel for half a minute. The mixing and standing are repeated until two consecutive tests give the same effect and this is taken as an indication of the behaviour in a countercurrent extraction column. The organic solvent may be the dibutyl ether of diethylene glycol which is used to extract plutonium and uranium, leaving fission products in the aqueous phase. Emulsification at the interface is caused by the presence of silica and may be avoided by boiling the aqueous solution for 12 hours or more.
