    Abstract: Metal compounds are removed from hydrocarbons such as crude oils, heavy distillate fuel oils, and diesel oils, by treating the hydrocarbon with a Schiffs base of salicylaldehyde or a substituted salicylaldehyde to convert the metal compounds into chelates, and then extracting the chelates with one or more carbonates of ethylene, propylene, or butylene. The carbonates of vinyl ethylene, styrene, and methoxypropylene may also be employed. The Schiffs bases are condensation products derived from 2 mols. of salicylaldehyde, which may be substituted by nitro, halogen, alkyl, nitrile, and other groups, and 1 mol. of a polyamine which has at least 3 nitrogen atoms in the molecule, for example dipropylene triamine, methyl dipropylene triamine, propyl dipropylene triamine, and butyl dipropylene triamine. Suitable substituted salicylaldehydes include mono nitrososalicylaldehyde and methylsalicylaldehyde. In examples the Schiffs bases employed were N,N1-disalicylidene-methylamine-dipropylene-diamine, N,N1-disalicylidene-ethylamine-dipropylene-diamine, and N,N1-disalicylidene-propylamine-dipropylene-diamine.

    Abstract: Liquid fuels, e.g. gasoline, jet fuel, diesel oil, gas oil and illuminating oil contain a phosphonic acid alkenyl ester monoamide of the formula in which R1 is alkyl, cycloalkyl, aryl, or aralkyl, R2 and R3 are hydrogen or alkyl or together form parts of a ring, and R and R1 may be hydrogen or alkyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, aryl, aralkyl, or alkenyl, or together may form parts of a ring. The fuels may also contain tetraethyl lead, iron carbonyl, aromatic amines, colourants and other additives.

    Abstract: The invention comprises alkyl alkynyl phosphoramidates of formula where R1 is alkyl, cycloalkyl, aryl or aralkyl, R2 and R3 are hydrogen or alkyl, or R2 and R3 together complete a cycloaliphatic ring, R is hydrogen, alkyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, aryl, aralkyl or alkenyl and R1 is alkyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, aryl, aralkyl or alkenyl, or R and R1 together complete a heterocyclic ring. They are prepared by reacting an alkyl alkynyl phosphorochloridate of formula with a primary or secondary amine, if desired, in the presence of an acid-binding agent and/or a diluent; temperatures of -20 DEG C. to +80 DEG C. or higher are mentioned. The products are stated to be pesticides. The phosphorochloridates, which are stated to be novel, are prepared by reacting alkyl phosphorodichloridates with acetylenic alcohols, the alcohol being added in small amounts at a time.
