Title: A process for removing friedel-crafts type catalyst from polymer product
IPC: C08F240/00
Filed: 1964-01-22
Abstract: Friedel-Crafts catalysts are removed from polymerized oils, obtained by polymerizing a steam-cracked petroleum hydrocarbon fraction boiling in the range 130-280 DEG  C. in the presence of the above catalyst, by treating the polymerized oil with dry ammonia or organic amines.  The monomer may be a steam-cracked naphtha oil.  The catalyst may be boron trifluoride gas or a 1:1 molar complex of boron trifluoride and ether.  The amine may be hexamethylene tetramine. After treatment of the polymerized oil with the ammonia or amine, a clear oil may be obtained by filtering off the precipitated matter and the clear oil may be distilled under reduced pressure to remove the low boiling fraction, or alternately, the clear oil may be washed with water.

Patent GB-581412-A (GB)
Title: Improvements in or relating to pressure-sensitive adhesives and adhesive tape made therefrom
IPC: C09J7/38
Filed: 1944-02-23
Abstract: A pressure-sensitive adhesive comprises as its essential ingredients cellulose nitrate and a polymerized heat-bodied non-drying oil, present in amount at least three times the weight of the cellulose nitrate, the adhesive being free from any solvent plasticiser for the cellulose nitrate.  The composition may be prepared in the presence of solvents such as benzene, alcohol, acetone, xylene, or mixtures thereof.  Heat-treated castor oil may be used as the polymerized non-drying oil.  Pigments or dyes such as titanium pigments, burnt umber, or coal-tar dyes, may be incorporated in the composition.  The ingredients may be mixed in any desired order.  In an example, a solution for forming a transparent adhesive comprises 4.5 per cent of cellulose nitrate, 23.6 per cent of heat-bodied castor oil, 3.5 per cent of ester gum and a solvent mixture comprising benzene, methylated spirit and acetone.  An adhesive tape is made by coating the solution on to a backing such as regenerated cellulose film, cellulose acetate film, or paper which has been treated to prevent undue penetration of the adhesive, e.g. paper which has been impregnated with a solution of glue, formaldehyde and glycerine.  The adhesive composition may be applied to one side of the backing with the aid of a spreading knife.  The solvents may be removed by passing the coated backing through a hot oven.  To provide better anchorage of the adhesive, the surface of the backing may be first treated with a primer.  A regenerated cellulose or cellulose acetate film may be primed with a solution or emulsion of casein and methyl methacrylate. A paper backing may be primed with an emulsion of p  methyl methacrylate or cellulose nitrate, or with a dilute solution of the adhesive.  Specification 575,678 is referred to.

Patent GB-711793-A (GB)
Title: Continuous alkylation process
IPC: C07C2/86
Filed: 1951-02-14
Abstract: An aromatic hydrocarbon is continuously alkylated by passing with an alkyl halide upwardly through a column of liquid catalyst produced from an aluminium halide and hydrocarbons obtained from catalyst spent in the alkylation reaction, withdrawing alkylation product and liquid catalyst from the upper part of the column and recycling said catalyst, after intermittent or continuous regeneration, to the column.  Mixing of reactants is effected by stirrers or baffles and by the liberated hydrogen halide which may be recycled in part to the base of the column.  Reactants and fresh liquid catalyst are fed to the base of the column, product and catalyst withdrawn at the top and passed to a gravity separator where catalyst is separated for recycle, aluminium chloride, generally 1-5 per cent, by weight, is added to compensate for losses, and circulation of liquid catalyst increased so that at least 1 volume is present per volume of reactants.  Small amounts of liquid catalyst are drawn off, continuously or at intervals, and replaced by fresh catalyst. Replacement of 2-5 per cent of the total every hour suffices. The drawn off catalyst is decomposed with water, and the separating oil or hydrocarbons distilled off therefrom mixed with fresh aluminium halide to form catalyst.  4-6 mols. of aromatic hydrocarbon per mol. of alkyl halide are advantageous, and conditions are correlated so that reaction is complete when reactants leave the column.  In examples, spent liquid catalyst prepared from aluminium chloride and a C12-alkyl benzene is decomposed with water and the oil layer distilled to yield hydrocarbons which are mixed with an equal weight of aluminium chloride to form the catalyst.  Benzene and alkyl chloride obtained by chlorinating a de-aromatized C12 petroleum fraction are reacted at 20 DEG  C.

In a modification, Fig. 5, the rotary member is carried by the shaft 26 of a toothed wheel which is adapted to roll on a toothed wheel 57 when its shaft is lifted against the pressure of springs 61 due to engagement of a press head with a large size fish. This rolling action increases the velocity of the press head. Specification 477,725 is referred to.
