Abstract

An organic liquid composition comprises a major proportion of a liquid light petroleum fraction boiling in the gasoline and/or kerosine boiling range and with a dielectric constant of 8 or less, and minor proportions of (A) a salt of a polyvalent metal and a alkyl salicylic acid having at least one alkyl substituent with 8 or more carbon atoms, and (B) a polymer of formula <FORM:1001942/C4-C5/1> in which R1, R2 and R3 are hydrogen atoms or hydrocarbon groups, R4 is a hydrocarbon group, and n is an integer, at least one of R1 and R2 being a hydrocarbon group, and certain provisos being attached to the size of R4 in relation to R3. Typical (A) additives are chromium, ferric, nickel, manganese and cobalt C14-18 alkyl salicylates; and typical (B) additives are homopolymers of N - 1 - propylbutyl methacrylamide, N-1,1,3,3-tetramethylbutylacrylamide, N,N - n - butyl - sec.amylmethacrylamide, a ,b -dimethylacrylamide and a ,b - dibenzyl acrylamide, many others being mentioned. A third additive (C) which may be present comprises a salt of dioctyl- or didecyl-sulphosuccinic ester, the salt-forming metals being as specified for (A). In examples, solutions of additives (A), (B) and (C) in xylene or gasoline are added to kerosine, and in some examples C14-18 alkyl phenol is also present.ALSO:Polymers of the amides listed below are prepared by treating a xylene solution of the amide with ditertiary butyl peroxide in a nitrogen atmosphere. The amides are N-1,1-dimethylethylmethacryl amide; N - n - butylmethacryl amide; N - 1 - methylbutylmethacryl amide; N - 1 - ethylbutylmethacryl amide; N - 1 - propylbutylmethacryl amide; N - 1 - methylheptylmethacryl amide; N - 1,1,3,3 - tetramethylbutylmethacryl amide; N - 1,1,3,3 - tetramethylbutylacryl amide; N - 3,5,5 - trimethylhexylmethacryl amide; N - n - decylmethacryl amide; N - 1 - methylpentadecylmethacryl amide; N - n - octadecylmethacryl amide; N,N-N,N - di - n - butylmethacrylamide; N,N-diisobutylmethacryl amide; N,N - n - butyl - secamylmethacryl amide; N,N - di - n - amylmethacryl amide; N,N - di - n - tridecylmethacryl amide; and N,N - di - n - butylacryl amide. It is also stated that poly (unsaturated amides) may be prepared from the corresponding poly (unsaturated ester) and an amine. Specific examples are the reaction of polymethylmethacrylate and n-octylamine to give polymeric N-n-octylmethacryl amide; and the reaction of polymethylacrylate with di-n-octylamine to give polymeric N,N-di-n-octylacryl amide.ALSO:N - n - butylmethacryl amide; N - 3,5,5 -tri-methylhexylmethacryl amide; N-n-decylmethacryl amide; and N-n-octadecylmethacryl amide are prepared from methacrylyl chloride and the appropriate primary amine. N - 1,1 - dimethylethylmethacryl amide is prepared from tert.-butyl alcohol and methacrylonitrile. N - 1 - methylbutylmethacryl amide; N-1-ethyl-butylmethacryl amide; N-1-propylbutylmethacryl amide; and N-1-methylheptylmethacryl amide are prepared from methacrylonitrile and the appropriate secondary alcohol, i.e. pentanol-2, hexanol-3, heptanol-4, and octanol-2 respectively. N - 1,1,3,3 - tetramethylbutylmethacryl amide and N - 1,1,3,3 - tetramethylbutylacryl amide are prepared by the addition of diisobutene and water on to methacrylonitrile and acrylonitrile respectively. N - 1 - methylpentadecylmethacryl amide is prepared from cetene-1 (hexadecene-1), water and methacrylonitrile. N,N - di - n - butylmethacryl amide; N,N - di-isobutylmethacryl amide; N,N - n - butyl - sec. -amylmethacryl amide; N,N - di - n - amylmethacryl amide; and N,N - di - n - tridecylmethacryl amide are prepared from methacrylyl chloride and the appropriate secondary amine. N,N-di-n-butylacryl amide is prepared from acrylyl chloride and di-n-butylamine.
