Abstract: Novel synthetic zeolite compositions of extremely small particle sizes that have increased loading capability, and process technology for producing such compositions are described. So far as is presently known, it has never been possible to form such compositions heretofore. The process technology involves, inter alia, contacting the zeolite cake formed in its production with a specified type of treating agent and then subjecting the treated zeolite to physical subdivision.

Abstract: The sizing agents are mixtures of alkenyl succinic anhydrides in which the alkenyl groups have in the range of about 6 to about 40 carbon atoms, and in which at least 97 wt % of the alkenyl groups are bifurcated on the alpha carbon atom into two branches neither of which has less than two carbon atoms. Other characteristics of the mixture are that (1) 20-50% of the bifurcated alkenyl groups have only one methyl or methylene substituent and no other side chain, and the remainder of such bifurcated groups have two straight chain branches (no side chain) emanating from the alpha carbon atom, (2) at least 3 alkenyl succinic anhydrides that differ in the number of alkenyl carbon atoms are each present in at least 5 wt % in the mixture, (3) no more than about 50 wt % of the alkenyl succinic anhydrides is any given alkenyl succinic anhydride or mixture of isomers having the same number of carbon atoms in their alkenyl groups, (4) the average number of carbon atoms in the alkenyl groups is ca.

Abstract: A cleaning process suitable for both mild and aggressive applications employs non-flammable, non-corrosive and environmentally friendly, fluorinated hydrobromocarbon solvent based cleaning compositions.

Abstract: A process for cleaning movie film, and especially cellulose acetate based polymer film, without causing film damage, comprises immersing the film into a cleaning solvent composition which comprises one or more halogenated hydrobromocarbons having from 1 to 3 carbons, from 1 to 3 bromine atoms and at least one chlorine or fluorine atom, such as 3-bromo-1,1,1-trifluoropropane, removing the film from the solvent and drying the film.

Abstract: Novel substituted phosphazene compounds are disclosed having the formula ##STR1## wherein w, x, y and z are integers the sum of which is from 3 to 6 with the proviso that w is at least 1 but equal to or less than (w+x+y+z)-1, x is from 1 to 5, y and z are from 0 to 2;R.sub.1 and R.sub.2 are the same or different and are C.sub.1 to C.sub.6 linear or branched alkyl;R.sub.3 is an unsubstituted or substituted aryl and n is 0 or an integer from 2 to 6; Q is --O--, ##STR2## --NR-- or --S--; Ar is ##STR3## R' and R" are the same or different and are C.sub.1 to C.sub.6 linear or branched alkyl, with the proviso that R" can also be hydrogen, wherein R.sub.1 and R.sub.2 are the same or different C.sub.1 to C.sub.4 linear or branched alkyl group and n is 0 or an integer from 2 to 6. These compounds display good solubilities in both organic and aqueous systems. Accordingly, they act as antioxidants in adhesive, sealant and coating compositions.

Abstract: Phenols, e.g. 2,6-di-tert-butylphenol, are coupled to form biphenols, e.g. 4,4'-bis(2,6-di-tert-butylphenol), by reaction with aqueous hydrogen peroxide under basic conditions in the presence of a phase transfer agent.

Abstract: A process of ortho-alkylating arylhydroxides, e.g., phenol, by passing a mixture of arylhydroxide, olefin and an inert hydrocarbon diluent in the liquid phase through a bed of activated alumina at an elevated temperature and pressure. Conversion and selectivity is improved over that obtained without the diluent.

Abstract: A process using heterogeneous resin-bonded aluminum phenoxide catalyst to alkylate phenols, the catalyst per se, and a process for making the catalyst. The inventive alkylation process uses ortho-tert-butylphenoxide bonded to a phenolformaldehyde condensation resin heterogeneous catalyst to prepare 2,6-di-tert-butylphenol from isobutylene and ortho-tert-butylphenol.

Abstract: A process for producing 2,4-di-substituted phenols wherein an olefin is reacted with phenol in the presence of a heterogeneous catalyst comprising an aluminum phenoxide bonded to an acidic solid polymeric resin to preferably form 2,4-di-substituted phenol.

Abstract: A process for the production of a 2,6-dialkylphenol in high yield wherein the alkyl groups are secondary or tertiary with a reduced overall production of 4-alkylphenol by-products by the aluminum phenoxide catalyzed pressure reaction of isobutylene with phenol and a mixture of 2,4-dialkylphenol and 2,4,6-trialkylphenol which may be obtained, in a cyclic process, as a bottom stream from the distillation of the reaction mixture to obtain the 2,6-dialkylphenol product.
