A magnesium phenate is prepared by a process which comprises reacting (1) magnesium oxide, magnesium hydroxide, magnesium carbonate, magnesium bicarbonate or a magnesium carboxylate with (2) a phenol, a methylene bis-phenol or a sulphurised phenol in the presence of (3) a solvent comprising an organic compound containing one or more alcoholic hydroxyl groups e.g. an alkoxy alcohol and (4) a promoter selected from a ketone, diketone such as α or β diketone, aldehyde or carboxylic acid and (5) optionally a diluent oil. This magnesium phenate may be used as a detergent for a lubricating oil.
A diphenylamine with both the phenyl groups being substituted is prepared by reacting a phenol with ammonia in the presence of a hydrogen transfer catalyst and a cyclohexanone; or by converting a portion of the phenol to the cyclohexanone in the presence of a hydrogen transfer catalyst and under hydrogen pressure and then reacting the remaining portion of the phenol with ammonia in the presence of the cyclohexanone so converted and the hydrogen transfer catalyst. The diphenylamine can be obtained very efficiently.

A latex for dip forming which comprises a copolymer prepared by polymerizing 10 to 90% by weight of a conjugated diene monomer, 0.1 to 20% by weight of an ethylenically unsaturated acid monomer and 10 to 89.9% by weight of other ethylenically unsaturated monomer or monomers copolymerizable therewith, wherein the sum of the amount of acid groups bonded to or adsorbed on the surface of the copolymer constituting the latex and the amount of acid groups present in the aqueous phase of the copolymer latex is in the range of 0.1 to 2 meq. in terms of hydrochloric acid, per gram of the copolymer. This latex is dip-formed to give a dip-formed article having no fear of development of a protein allergy, and exhibiting a soft feeling and a high mechanical strength.
