Title: Improvements in the manufacture of ºÔ-cymene hydroperoxide
IPC: C07C409/08
Filed: 1953-09-18
Abstract: a  : a  - Dimethyl - p - methylbenzyl hydroperoxide is made by a process of contacting p-cymene in the homogeneous liquid phase under substantially anhydrous conditions (i.e. less than 5 per cent of water in the liquid state), and in the absence of a catalyst, with an excess of commercial oxygen at a temperature of 105-150 DEG  C., preferably from 130-150 DEG  C., wherein the explosion risk in the gas space above the reaction mixture is reduced by the introduction of steam in an amount given by the equation <FORM:0737971/IV (b)/1> where A is the minimum concentration of steam allowable in volume per cent of the gaseous mixture, calculated after deduction of the p-cymene vapours, and t is the temperature in degrees centigrade.

Title: Rubbery graft polymers
IPC: C08F279/02
Filed: 1961-07-17
Abstract: Rubbery polymers derived from one or more unsaturated hydrocarbons are reacted in solution in an inert organic solvent with a hydroperoxide, an aldehyde or aldehyde forming substance, or a mercaptan in the presence of oxygen to obtain an activated polymer, which is then reacted with a polymerizable unsaturated monomer to form a graft polymer. Rubbery polymers specified are homopolymers of isobutylene and butadiene, and copolymers such as isobutylene/butadiene, isobutylene/isoprene and ethylene/1-butene. Polymerizable monomers specified are styrene, vinyl diphenyl and naphthalene, acrylic acid, amide, esters, nitriles and chloride, vinyl ketones, vinyl carbazole, vinyl pyridines, butadiene and hanologues thereof, chlorobutadiene, cyclopentadiene and alkylcyclopentadienes.  Hydroperoxides specified are tert.-butyl, cumene, cyclohexanone and cycloalkyl hydroperoxides. If desired, the hydroperoxide may be formed in situ by treating a mixture of polymer and an isoparaffin with oxygen.  Mercaptans specified are mercaptoacetic acid and the reaction products of hydrogen sulphide with ethylene oxide, sulphide or imine.  Aldehydes or aldehyde-forming substance specified are formaldehyde, paraformaldehyde or a mixture of carbon monoxide and hydrogen peroxide. In the case of polymers activated by aldehydes the polymerization of the grafting monomer may be initiated by metal salts, e.g. those of cobalt, copper, cerium, iron and manganese. When the resulting products contain double bonds they may be vulcanised. The examples describe the following processes: (1) treating an isobutylene/ isoprene copolymer with tert.-butyl hydroperoxide and grafting methyl acrylate thereon in solution in hexane to yield a vulcanisable product; (2) as in (1) applied to an isobutylene/ piperylene copolymer; (3) treating an ethylene/ 1-butene copolymer with tert.-butyl hydroperoxide and grafting acrylic acid thereon in solution in hexane; (4) as in (3) but using an isobutylene/isoprene copolymer to yield a product which reacts with phenyl isocyanate; (5) treating an isobutylene/butadiene copolymer with mercaptoacetic acid and air and grafting methyl acrylate thereon in the absence of solvent; and (6) treating an isobutylene/isoprene copolymer with paraformaldehyde and (in latex form) grafting methyl acrylate thereon to yield a vulcanisable product.

In pulping apples &c. by steam cooking the apples are caused to rub against one another to remove each outer layer as it is softened by the cooking so as to quicken the operation, rings 7 being provided inside an apple-receiving inner perforated rotating cylinder 5 to slow up the movement of the apples from the right hand end to the left, and so give sufficient time for the rubbing action. The apples are fed from a hopper 10 by a screw conveyer 9 to the inside of the open ended rotated cylinder 5 which is perforated so that the pulp, when formed, passes through to the annular space between the inner and outer cylinders 1 along which it is traversed to the outlet 13 by a helical rib 8 on the outside of the inner cylinder 5. Steam from a pipe 3 enters the outer cylinder 1 through nozzles 2 and flows generally in counter direction to, the feed of the apples and passes out through the hopper 10, since the pulp outlet 13 forms a trap. The steam from the nozzles 2 keeps clear the perforations 6 in the inner cylinder 5. The left over cores pass out through the end of the cylinder 5 and drop down into the pulp outlet 13.
