A method for cleaning the interior surfaces of a receptacle holding a body of water comprises providing the receptacle, providing an aqueous solution having from about 1 to about 100 weight percent of an aliphatic amine or salt thereof, adding the aqueous solution to the water within the receptacle. The aliphatic amine is selected from among the following: CH,CH,CH,CH,CH,CH,CH,CH,CH,CH,NH,, R&mdash;O&mdash;(CH,),NH,and R&mdash;O&mdash;(CH,),NH(CH,),NH,wherein R is an aliphatic hydrocarbon having from 8 to 10 carbon atoms, R optionally having additional ether linkages such as C,H,&mdash;(O&mdash;CH,CH,),&prime;, and wherein n is an integer from 8 to 10 and n&prime; is an integer from 1 to 5. When the aqueous solution is added to the water, flocculus or precipitants are substantially not formed in the water proximate to the point of addition. Also disclosed is a swimming pool having a liner and a body of water within the liner. The body of water has from about 1 to about 100 parts per million by weight of an aliphatic amine or salt thereof.

The instant invention is directed to a process for removing odor from alkylthioethylamine reaction product mixtures having said odor. The process comprises first contacting an alkylthioethanamine reaction product mixture with a neutralizing amount of aqueous alkali metal hydroxide to form an organic phase and an aqueous phase. Next, the organic phase is separated from the aqueous phase. After separation, a sufficient amount of an aqueous hydrohalic acid is added to the organic phase to form an alkylthioethanamine hydrohalide which has reduced odor.

Novel polyamines are disclosed which consist essentially of linear chains of the formula ##STR1## WHEREIN R is H or the acyl group of a fatty acid or an alkylsulfonic acid and n is a number about 6-22. Of the n units in the chain, in about 0 to 50% R is an acyl group of about 20-150 carbon atoms, in about 5-75% R is an acyl group of about 1-18 carbon atoms and in about 10-90% R is H. The compounds are made by appropriate partial acylation of the corresponding polyethylenepolyamine or by (a) polymerizing a 2-alkyl-2-oxazoline and then partially hydrolyzing and reacylating the polymer thus obtained. They are useful as surfactants, especially as detergents in lubricating oils.

An oil filter is disclosed as having a filter enclosure provided with oil inlet and outlet ports adapted for communication with the oil circulating system of an associated oil lubricated engine. Disposed within the enclosure is a filter element fabricated of any suitable filtering media. In addition to the filter element, a body of an oil soluble, relatively solid polymer having oil additives compounded therein is disposed within the enclosure. The polymer body is located within the enclosure so as to be in an area where minimum oil flow occurs, i.e. in a relatively non-turbulent oil flow area, which results in the polymer dissolving at a relatively uniform or linear rate so as to prevent undesirable concentrations of the additives during the effective service life of the filter. If desired, suitable baffle means may be interposed between the area of primary oil flow within the filter and the oil soluble polymer, whereby to provide for the controlled contact of the flow of turbulent oil within the filter with the polymer body and thereby assure the desired linear or uniform rate of polymer dissolution.
