Abstract: 555,081. Lubricating oil compositions. STANDARD OIL DEVELOPMENT CO. Sept 2, 1940, No. 13767. Convention date. Oct. 4, 1939. Drawings to Specification. [Class 91] [Also in Group IV] Addition agents for lubricating oils designed to improve the pour point and colour characteristics are prepared by condensing an aromatic hydrocarbon, or a halogen derivative thereof, containing 1-4 rings preferably fused rings, with a monohalogenated aliphatic hydrocarbon containing from 1-5 carbon atoms or a mono-olefine containing 2-5 carbon atoms and with a polyhalogenated aliphatic hydrocarbon in the presence of a Friedel-Crafts condensing agent such as aluminium chloride, zinc chloride or boron fluoride, or an acid catalyst such as sulphuric or phosphoric acids. The compounds thus obtained may be improved by a further condensation with a halogenated high molecular weight hydrocarbon such as a chlorinated paraffin wax or a corresponding unsaturated hydrocarbon in the presence of one of the above mentioned condensing agents. The primary condensation is preferably carried out in two stages, in the first of which the mixture is heated to a relatively low temperature such as 85‹-90‹F. to effect a first stage condensation, after which the reaction mixture is refluxed for 2-4 hours. An inert solvent may be present if desired. In Example (1), naphthalene was condensed with ethylene chloride and amyl chloride in the presence of aluminium chloride, first at 90‹ F. and then refluxed at 210‹-230‹ F. The reaction mixture was worked up by hydrolysis with alcohol and water and the etnylene chloride extract distilled. From an intermediate fraction a compound was obtained which was identified as di-(amylnaphthyl) ethane. Example (2) was conducted as in example (1) but with a longer reaction time. Example (3) was conducted as in example 1, but the condensation product was subjected to a further condensation with chlorinated paraffin wax. Example (4) was conducted similarly to example (3) using slightly modified quantities of reactants and times of reaction. Example (5) was conducted as in example (3) except that in place of the low boiling aliphatic monohalide amyl chloride, the corresponding olefine amylene was used. Example (6) was conducted as in example (1) except that the reaction was carried out in a large scale plant, a drawing of which is furnished. Tests are given to show the pour depressant potency and also the effect on the colour of oils of the products of the invention.
