Abstract: A cable insulating composition comprises a mineral oil of the type used for cable insulating oils and between 5 and 50 per cent. by weight of rosin which has been purified by dissolving it in a hydrocarbon solvent, treating the solution with an absorbent comprising silicious earth such as Fuller's earth, Florida earth, Montmorillonite, silica gel or adsorbent, preferably activated carbon such as activated charcoal and recovering the purified rosin from the solvent. The rosin may be dissolved in paraffinic or naphthenic hydrocarbons, aromatic solvents or terpenes, and the treatment may be by agitating the liquid with the adsorbent, or by percolating it through the latter. Desorption of the rosin from the adsorbent may be assisted by washing the adsorbent after treatment with a solvent, which may or may not be the same as that originally used to dissolve the rosin. In an example, Portuguese rosin (colour K) is dissolved in a petroleum fraction boiling between 60 DEG C. and 80 DEG C., and the solution percolated through a column of activated animal charcoal. After washing the column through with an equal volume of solvent, the rosin is desorbed by elution with pure benzene, which on evaporation gives a pale yellow crystalline product of colour X. Comparative figures for the power factor of this product and of the untreated and conventionally purified rosin when dissolved in a clay-treated bright paraffinic stock are given.

Abstract: Hydroxyl aryl-substituted fatty acids in which the non-aryl portion contains 10-30 carbon atoms are prepared by the reaction of a phenol with a fatty acid or ester or a nitrile, and hydrolysis of the ester or nitrile to the acid. If unsaturated acids, esters or nitriles are used they are first chlorinated and then reacted with the phenol. Fatty acids and esters referred to are undecylenic, lauroleic, myristoleic, palmitoleic, oleic, gadoleic, erucic, ricinoleic, linoleic, linolenic, elaeostearic, licanic, arachidonic and clupanodonic acids and glyceryl oleate. Phenols specified are phenol, cresols, naphthols such as alpha and beta naphthols and alkyl and aryl naphthols and di- and tri-hydric phenols such as resorcinol, catechol and pyrogallol. In an example phenol, BF3 and oleic acid are mixed in a flask. The reaction mixture, after cooling and standing for 20 hours, is diluted with toluene, washed with water containing a little isopropyl alcohol and steam distilled to obtain hydroxy-phenyl stearic acid. Metal soaps of the above hydroxyl aryl-substituted fatty acids, such as the alkali or alkaline earth metal soaps, form complexes with low molecular weight salts, for example of acetic, furoic, acrylic, crotonic and ethoxypropionic acids, for example sodium acetate.ALSO:A lubricating grease comprises a lubricating oil and a metallic soap of an aryl-substituted fatty acid, the aryl group thereof containing a free hydroxyl group, and the non-aryl portion containing 10-30 carbon atoms. The aryl-substituted fatty acid may be one formed by the reaction of a fatty acid or ester or a nitrile with a phenol. Fatty acids and esters referred to are undecylenic, lauroleic, myristoleic, palmitoleic, oleic, gadoleic, erucic, ricinoleic, linoleic, linolenic, elaeostearic, licanic, arachidonic, and cluparodonic acids and glyceryl oleate. Phenols specified are phenol, cresols, naphthols such as alpha and beta naphthols and alkyl and aryl naphthols and di- and tri-hydric phenols such as resorcinol, catechol and pyrogallol. The esters and nitriles are hydrolized to the acid after reaction with the phenol. Hydroxyphenyl stearic acid is specified. The metal soap may be an alkali or alkaline earth metal, for example sodium or lithium, soap. Lubricating oils referred to are mineral oils and synthetic oils such as the branched chain esters of dibasic acids, for example di-2-ethyl hexyl sebacate, and complex esters formed by reacting together a glycol or polyglycol and a dibasic acid and an alcohol. Optional ingredients specified are soaps, for example lithium stearate, and low molecular weight salts, for example of acetic, furoic, acrylic, crotonic and ethoxypropionic acids. Examples are given of the preparation of the greases.

Abstract: Cyclopentadiene and methyl cyclopentadiene are separated from the vapour phase products of cracking a hydrocarbon fraction by quenching and segregating a vapour phase stream containing C1-C9 hydrocarbons, substantially no dimers of the cyclopentadienes being formed, compressing and cooling this stream to condense out most of the C6+hydrocarbons together with some C5 and a small amount of lower, stripping the lower hydrocarbons from the C6+, passing the latter to a dimerization zone, fractionating from the C10 and C12 dimers, C5-9C hydrocarbons to recover a concentrate of cyclopentadiene and methyl cyclopentadiene dimers which is dedimerized and the resulting monomers separated by fractionation. Gas oil, kerosine or naphtha boiling between 250 DEG and 700 DEG F. is cracked in admixture with 50-90 mol. per cent of steam at 1000-1600 DEG F. and 1-10 atm. total pressure for a period of 1-5 secs. The product, at a pressure of about 0-100 p.s.i.g., is quenched to about 350-650 DEG F. by injection of water and cycle oil and fed to a fractionator operating at about 0-10 p.s.i.g. giving an overhead of C1 to C9 containing nearly all the cyclopentadiene and homologue, a cycle oil condensate, and a bottom tar stream. The overhead is cooled rapidly to 90-135 DEG F. to condense C10+ hydrocarbons, and steam, and then further compressed and cooled to about 40-210 p.s.i.g. and 90-135 DEG F. to condense further water and C6+ hydrocarbons, including most of the methyl cyclopentadiene. The remaining vapours containing cyclopentadiene and mainly C1-C5 hydrocarbons may be purified and dried before compressing and cooling, e.g. with liquid propene or ammonia, to liquify C5+ hydrocarbons, andfr actionating at about 80-90 p.s.i.g. to give a bottom C5+ liquid which may be soaked at 150-250 DEG F. to dimerize the cyclic dienes, and fractionated to recover cyclopentadiene dimer. Alternatively, the C5+ liquid may be processed together with the C6+ condensate containing most of the methyl cyclopentadiene. This condensate is first stripped to remove C3-C5 hydrocarbons, soaked to dimerize cyclic dienes, and fractionated to recover a dimer concentrate. The homologous dienes are separated from the conconcentrates by dedimerizing at 300-650 DEG F. and fractionation of the vapours.
