Definitions

  • the present invention relates to a method for preventing the growth of aerobic fungi in aqueous hydrocarbons, for example middle distillate fuels, by addition thereto of a material having biostatic activity and to aqueous hydrocarbon compositions containing such material having biostatic activity.
  • compositions comprising a hydrocarbyl-substituted succinimide in which the hydrocarbyl substituent is of sufficient size to impart hydrocarbon solubility and boron provides at least some of the aforesaid needs.
  • US-A-4,092,127 discloses a fuel to which has been added, in an amount sufficient to provide from about 80 to 400 parts per million by weight of boron of an anti-dieseling combination of:-
  • US-A-4,184,851 discloses a fuel composition which comprises a major proportion, i.e. more than 50% by weight, of a distillate petroleum fraction preferably having an atmospheric boiling range of from about 120°C to about 400°C and from about 0.001 to 1.0 wt % of borated oil-soluble succinamic acid or its derivative having the following formula:- wherein R is a straight chain aliphatic hydrocarbon group having from 0 to 1 site of olefinic unsaturation (alkyl or alkenyl) attached at a secondary carbon atom to the succinyl group and is of at least 8 carbon atoms, generally in the range of 14 to 40 carbon atoms and more usually in the range of 15 to 30 carbon atoms; one of X and X1 is hydroxyl and the other is -NYY 1 wherein N has its normal meaning of nitrogen and Y and Y1 are aliphatic hydrocarbyl groups of from 8 to 40 carbon atoms, more usually of from 14 to 30 carbon atoms,
  • Hydrocarbyl-substituted succinimides are well known as dispersant additives in lubricating oils, see for example GB-A-922,831; GB-A-1565627 and EP-A-0031236 as representative of the extensive patent literature on this subject. Both mono- and bis-succinimides may be employed.
  • the hydrocarbyl substituent contains from 40 to 150 carbon atoms.
  • the substantially saturated hydrocarbyl group is preferably derived from a polyolefin, more preferably from a polyisobutene.
  • the boric acid or salt thereof may be present in the additive either in the form of a physical admixture with or chemically bound to the hydrocarbyl-substituted succinimide.
  • the boric acid or salt thereof is preferably present in the form of a particulate dispersion, suitably incorporating also a carrier for the boric acid or salt thereof.
  • the boric acid salt is preferably in the form of the ammonium salt of boric acid.
  • the carrier may be a hydrocarbon-compatible high-boiling material. Suitable carrier materials include mineral oils which may be solvent refined or otherwise, synthetic lubricating oils, for example of the ester type, liquid polyolefins, for example low molecular weight polyisobutenes, or their oxidised or aminated derivatives, amino and hydroxy derivatives of polyolefins, or liquid olefin copolymers.
  • the carrier may also comprise the hydrocarbyl succinimide component.
  • the mean particle size of the particulate dispersion may suitably be less than 1 ⁇ m, preferably less than 0.5 ⁇ m.
  • a suitable dispersion of the boric acid or salt thereof may be prepared by wholly or partially desolvating a solvent-in-carrier emulsion of a solution of the boric acid or salt thereof in the presence or absence of the hydrocarbyl-substituted succinimide, preferably in its presence.
  • Suitable solvents for the boric acid or salt thereof include hydrocarbons and substituted hydrocarbons of relatively low boiling point and water, water being preferred.
  • the hydrocarbon may be any of diesel fuel, heavy marine fuels and fuel oils, including both domestic and industrial heating oils. Whatever, the hydrocarbon, it is contaminated with water, which may be present in amounts as low as 0.1% w/w, or less.
  • the amount of the additive suitably employed may conveniently be defined in terms of the amount of boron incorporated into the fuel.
  • the amount of additive used must be sufficient to provide up to 500, more suitably up to 200 ppm wt in the hydrocarbon.
  • the additive may suitably be compounded with other additives conventionally employed in fuel compositions, for example in the case of a diesel fuel composition the additive package may further incorporate at least one of an anti-rust agent, an anti-foam agent, an antioxidant and a demulsifier. It is an advantage of the additives of the present invention that in addition to providing biostatic activity, they also provide dispersant properties, i.e. they behave as multifunctional additives.
  • polyisobutene mono-succinimide designated hereinafter as PMS
  • PMS polyisobutene (molecular weight about 1000) substituted succinic anhydride 1:1 adduct of tetraethylpentamine (TEPA)
  • PBS polyisobutene bis-succinimide
  • PBS polyisobutene (molecular weight about 1000) substituted succinic anhydride 2:1 product of TEPA was employed.
  • test fuels A - H were tested with 4 fungal strains using a method described by Smith and Crook. [The germination and growth of Cladosporium resinae in fuel oil, 'Biodeterioration. The Proceedings of the Fourth International Biodeterioration Symposium, Berlin' (T.A. Oxley, G. Becker and D. Allsopp, eds) Pitman, London, pp 29-36, 1980].
  • sterile aqueous medium in test tubes is innoculated with a suspension of fungal spores and then overlaid with fuel containing known levels of test additives. Tubes are incubated for ca . 28 days and examined periodically for development of the fungi at the fuel/water interface.
  • test fuel (I) containing no additive was tested.
  • test fuel (Biobor JF, ex US Borax) was tested in test fuels X and Y (270 ppm level).
  • Mould cultures were grown initially on Sabouraud Dextrose Agar slopes (5 slopes of each strain) for 10 days at 27°C. Sterile quarter strength Ringers solution (5 ml) was added to each slope and shaken to obtain a conidial (spore) suspension. The suspensions were then spun in a Sorvall Superspeed centrifuge type SS3 at 5000 rpm for 15 minutes. The conidial pellet was washed once with sterile quarter strength Ringers solution and the suspension adjusted to give a final concentration of 106 conidia per ml.
  • Mains tap water, enriched with 10% Bushnell and Haas medium a mineral salts medium for the culture of hydrocarbon utilising fungi consisting of NH4N03 (1 g), KH2PO4 (1 g), K2HPO4 (1 g), MgS04 (0.2 g), FeCl3 (0.01 g), CaCl2 (0.02 g), distilled water (1 litre), pH 7.0 ⁇ 0.3, autoclaved at 121°C for 15 minutes (Bushnell, L.D. and Haas, H.F., J.
  • yeast extract was dispensed in 2.5 ml aliquots in 20 ml Bellco screw capped glass test-tubes and then sterilised by autoclaving at 121°C for 15 minutes. A series of tubes was then inoculated with 1 drop of conidial suspension using a sterile Pasteur pipette. A 2.5 ml aliquot of test fuel was then overlaid on the aqueous medium. Uninoculated aqueous medium overlaid with test fuel was used as control. Five replicates were used for each fuel sample. The procedure was repeated for all four test species.
  • control fuels i.e. diesel fuel minus additives and diesel fuel containing the jet fuel biocide, Biobor JF (Borax Holdings Limited) at a concentration of 270 ppm (20 ppm boron), were laid over inoculated and uninoculated medium as above.
  • SCORE A The degree of fungal colony development in the water was estimated as nil (0), feeble (+), good (++) or very good (+++) and this was converted to a numerical score, viz 0, 1, 2 or 3 (SCORE B).
  • Biobor JF was ineffective in protecting the interface except in the case of Cladosporium .
