Abstract of the disclosure Protection of non-aqueous systems with biocides Non-aqueous and water-insoluble industrial materials are stabilised and protected against attack by harmful micro-organisms by incorporating in the systems to be stabilised phosphonium chlorides of formula 1 (C4Hg)3PCnH2n+1?Cl?(I) wherein n is an integer from 8 to 16.
Description
~ ~7~
Protection of non-aqueous svstems with biocides The present invention relates to a process for stabilising non-aqueous systems against attack by harmful organisms using phosphonium chlorides.
Phosphonium chlorides have microbiological activity. A process for treating water using phosphonium halides as biocides is disclosed, for example, in EP-B-0 066 544. The use of non-hygroscopic phosphonium tetrafluoroborates or phosphonium hexafluorophosphates as biocides for industrial material protection is disclosed in EP-A-0 332 578. Antiseptic detergent compositions containing phosphonium halides are~disclosed in US-A-3 281 365.
There is still a need to protect non-aqueous systems effectively against attack by harmful organisms.
Surprisingly, it has now been found that specific alkyltributylphosphonium chlorides, although in contrast to the corresponding tetrafluoroborates they have hygroscopic properties and are soluble ~o an unlimited degree in water, are admirably suited for protecting non-aqueous systems.
The invention accordingly relates to a process for stabilising non-aqueous and water-insoluble industrial materials against attack by harmful organisms, which comprises incorporating in the system to be stabilised phosphonium chlorides of formula I
[(C4H9)3 PCnH2n+1] Cl (I) wherein n is an in~teger from 8 to 16.
The C"H2n+l radical at the phosphorus atom may be linear or branched and and is typically octyl, nonyl, decyl, dodecyl, tetradecyl, pentadecyl or hexadecyl.
The preparation of the biocides used in the process of this invention is known to the skilled person and is described, for example, in US patent specification 3 281 365. Thus the compounds may be typically prepared by alkylating tertiary phosphines with aLkyl halides:
R3P + Hal-R ~ [R3P-R ] Hal Alternative methods are the alkylation of phosphanes (also secondary and tertiary~ or of elemental phosphorus ~q.v. Houben-Weyl, Methoden der Organischen Chemie, Vol. XII,~L, page 79, Georg Thieme Verlag, Stuttgart, 1963; Houben-Weyl, Methoden der Organischen Chemie, Vol. E,1, page 491 et seq., Georg Thieme Verlag, Stuttgart, 1982.) It is expedient to dissolve the compounds of formula Ij in some cases directly after their synthesis, in an organic solvent or mixture of solvents and to incorporate them in the material to be stabilised. Before incorporation, such solutions may contain compounds of forrnula I in high concentration, e.g. 30-80 %, preferably 40-70, most preferably 45-60 %
by weight of the solution.
If such solutions of biocides of formula I are incorporated, for example, in antifouling paints, then it is best to use a solvent or mixture of solvents which is the same as that also used for the paint system. It is not necessary to remove the respective solvent from the formulation, as it evaporates when the finished coat dries.
Solvents suitable for use in the process of this invention include hydrocarbons such as toluene or xylene. High-boiling mineral oils or products customarily used as paint solvents are also suitable, typically ketones or esters, such as butyl acetate or polyglycols.
Particularly suitable solvents are those in which the compounds of formula I are at le~st 40 %, preferably 50 %, soluble.
The compounds of formula I have a particularly good activity against harmful organisms that attack industrial materials.
Illustrative examples of materials which can be protected by the process of this invention are typically plastics materials, coatings (e.g. paints and varnishes), dyes (dye formulations), rubber and adhesives.

Particularly suitable solvents are those in which the compounds of formula I are at le~st 40 %, preferably 50 %, soluble.
The compounds of formula I have a particularly good activity against harmful organisms that attack industrial materials.
Illustrative examples of materials which can be protected by the process of this invention are typically plastics materials, coatings (e.g. paints and varnishes), dyes (dye formulations), rubber and adhesives.
It is particularly advantageous lo use the biocides of forMula I for protecting plastics materials, p~ints and varnishes, espec~ally those for exterior use, but first and foremost also for protecting antifouling paints.
The paints (paint formulations) to be protected are preferably antifouling paints. These paints contain as binder the customary polymers known to those skilled in the art, typically natural and synthetic resins, homopolymers and copolymers of the monomers vinyl chloride, vinylidene chloride, styrene, vinyl toluene, vinyl esters, vinyl alcohols, acrylic acid and methacrylic acid, as well as their esters, polyester and polyamide resins, and also chlorinated rubber, natural and synthetic rubber, which may be chlorinated or cyclised, also reaction resins such as epoxy resins, polyurethane resins, unsaturated polyesters which may be converted into film-forming products of high molecular weight by adding hardeners.
The binders may be liquid or in the form of solutions. Solid coating compositions can be applied to objects by powder coating techniques. Other conventional basic components are typically tar, modifiers, dyes, inorganic or organic pigments, fillers and hardeners.
The process of this invention is utilised especially wherever objects which it is desired to protect against the growth of fungi arld algae and infestation by balanidae, bryozoa, hydroida, molluscs, protozoa, mussels and bacteria are exposed to water, especially seawater. Such objects are in particular ships' hulls, hydraulic structures, buoys or f1shing nets, and also cooling and pipe systems around or through which water flows. Quite generally the process of this invention makes it possible to protect all materials which can come in contact with water from growth or infestation by the cited organisms.
Accordingly, a preferred process is one wherein the compounds of formula I are used in antifouling paints.
A preferred process is also one wherein the compounds of forrnula I are used in paint formulations for objects which are submerged in water, especially seawater.
The amount of compounds of formula I which is used and added to the industrial materials in the process of this invention will naturally depend sobstantially on the respective utility and can therefore vary over a wide range. Depending on the envisaged end use, the compounds are used in the concentration ranges which are known to those skilled in the art.
Owing to the wide spectrum of use, concentrations of 0.1 to 40 % by weight of cornpound of formola I, based on the substrate to be treated, are suitable. Typical concentrations for treating plastics materials, such as plasdcised PVC sheets, are 0.1 to 10 % by weight, preferably 0.1 to 5 % by weight; 0.1 to 40 % by weight, preferably 0.5 to 40 % by weight, for example 10 to 40 by weight, in paint formulations such as antifouling paints.
A preferred field of use is that for protective coatings, especially for antifouling paints, to which are added, besides conventional basic and modifier components, typically 0.5 to 40 % by weight, preferably 5 to 40 % by weight, based on the total mixture, of at least one compound of formula I.
The compounds of formula I, which are dissolved in organic solvents, can be applied in pure form or together with carriers such as formuladon auxiliaries. They can also be suspended in liquid coating composidons and the like, in which case wetting agents can promote the uniform dispersion of the active compound to form homogeneous dispersions.
Further biocides may also be added.
A further utility of the compounds of formula I is incorporation in plastics materials, including polyvinyl chlorides and their co- and heteropolymers, polyalkylenes, including polyisobutylene, polyacrylates, polystyrenes, copolymers thereof, polyurethanes or polyisocyanates, polyesters, epoxy resins and the like, or in natural or synthetic rubbers.
The process of the invention can be used with advantage for providing plastics materials, including polyamides, polyurethane foams or polyisobutylene, with preservative finishes.
When using plasticisers, it is best to add a solution or dispersion of the biocide in the plasdciser to the plastics material. The antimicrobially treated pLIstics materials can be used for fabricating useful articles of all kinds for which effective protection against the most diverse germs, such as bacteria and fungi, is desired, for example plasticised PVC
sheets, foot-mats, bathroom curtains, seats, swimming pool steps, wall coverings and the like.
The compounds of formula I can also be used for elastomer coatings as well as for silicone elastomers and fluorine-containing polymers. In this connection it is expedient to use preferably high-boiling solvents, which in some cases remain in the finished product.
~g~3~75~3 A particularly advantageolls utility is incorporation in plastics or polymer materials which are used as building materials and are exposed to atmospheric influences, or which are used in the humid and moist sectors. Such materials may typically be rooflng materials or facings of polyvinyl chloride, butyl rubber, chlorinated polyethylene, polyisobutylene, chloroprene and chloroisoprene, ~PDM as well as PVC copolymers with vinyl acetate or ethyl vinyl acetate, polyacrylonitrile-styrene, by themselves or in admixture with fibrous fillers (in some cases also blended with bitumen), or foamed polyvinyl chlorides or polystyrenes as insulating materials against heat and cold.
In practice, biocides are often used in conjunction with other biocides. In the process of this invention too it is possible to use further biocides. Combinations of biocides are also useful in antifouling compositions. Hence the phosphonium chlorides of formula ~, in conjunction with, for example, Cu20, CuSCN, zinc oxide, triorganotin compaunds, such as tributyltin fluoride, triphenyltin chloride or tributyltin-containing polymers, metallic copper or triazines such as 2-methylthio-4-tert-butylamino-6-cyclopropylamino-s-triazine, can normally be combined with such compounds which are known to those skilled in the art as being effective against animal or vegetable growth.
It will be furthermore be readily underst()od that these combinations may additionally contain the substances and auxiliaries which are customarily concurrently used in such formulations. These additional substances include anionic, cationic or nonionic surfactants, electrolytes, chelating agents, solubilisers as well as dyes and aromatic substances. These ingredients are used typically to enhance the wetting capacity and hardening stability, to adjust the viscosity, and to enhance cold resistance.
The invention also relates to a process in which at least one further biocide is addded.
A particular advantage of the compounds is that their broad activity spectrum is achieved without the presence of a metal atom. Compared with the use of metal-containing biocides, the use of the biocides in the practice of this invention is ecologically more favourable.
As mentioned at the outset, in contrast to the corresponding tetrafluoroborates ordinarily used in non-aqueous materials, the alkyltributylphosphonium chlorides are hygroscopic.
They can therefore be incorporated without difficulty in aqueous systems. Their 7~13 incorporation in solvent-based paints, antit`ouling paints, coating compositions for surface protection or in polymer articles such as roofing memb~anes, rubber balls and the like, was therefore previously not known. Surprisingly, the process of this invention makes it possible to incorporate the compounds in such non-aqueous organic systems. It isespecially surprising that the, despite their very ~good aqueous solubility, the biocides cannot be dissolved, or can be dissolved only to an insignificant extent, out of these materials.
The following Examples illustrate the invention in more detail. In particular, they demonstrate the good effectiveness of the compounds of formula I in non-aqueous systems. In these Examples, and also throughout the description and in the claims, parts and percentages are by weight, unless othwerwise indicated.
Example 1: Tri-n-butyltetradecylphosphonium chloride is dissolved in xylene to give a 50 % solution, which is used to prepare an antifouling formulation based on vinyl/colophonium (1:1) and 20 % of fillèr in the manner known to those skilled in the art.
The amount of phosphonium compound is computed such that it comprises 22 % by weight in the dry film. The antifouling formulation is applied to microscopic slides conventionally llsed in microscopy. After drying for 3 days, one of these samples is kept for 1 week in artifical seawàter. After this time, this sample and a sample which has not been kepî in water are analysed. Analysis is made by 3IP-NMR spectroscopy. This is done by scratching off the coatings and weighing the scrapings. After the addition oftriphenylphosphine as internal standard, deuterised chloroform is added and the batch is ultrasonicated for 3 hours. After separation of the solids by centrifugation, a 31P-NMR spectrum of the solution is recorded, accumulating 42 000 scans. Correction factors for the peaks are determined by way of a quantitative inverse-gated image. The following analytical values are obtained:
concentration of tributyltetradecylphosphonium chloride in the sample which has not been kept in water: 20 %
concentration of tributyltetradecylphosphonium chloride in the sample which has been kept in water: 22 %
The analysis shows that the phosphonium compound has not leached out after immersion for 1 week in water. A less than the theoretical percentage concentration is found in the sample which has not been immersed in water. The explanation of this finding is that the solvents have not yet volatilised completely prior to immersion in water, thereby resulting in a higher "dilution" results.
A t S1~3 Example 2: Tributyltetradecylphosphonium chloridle is added to a commercially available wood sealing varnish ("Classic" filler-free varnish, ex Decor GmbH, Hamburg) such that the liquid formulation contains 3 % of the compound. The formulation is applied, stored and analysed as described in Example 1. The following analytical values are obtained:
concentration of tributyltetradecylphosphonium chloride in the sample which has not been kept in water: 11 %
concentration of tributyltetradecylphosphonium chloride in the sample which has been kept in water for 1 week: 8 %
Example 3: The antifouling paint formulation of Example 1 is applied to specimen plates to test the growth resistance to seawater organisms. Plates coated with the biocidally-treated paint formulation are free from growth after immersion for 12 and 39 weeks in the North Sea. Plates coated with the same formulation, but without biocide, are completely overgrown even after immersion for 12 weeks.
The paints (paint formulations) to be protected are preferably antifouling paints. These paints contain as binder the customary polymers known to those skilled in the art, typically natural and synthetic resins, homopolymers and copolymers of the monomers vinyl chloride, vinylidene chloride, styrene, vinyl toluene, vinyl esters, vinyl alcohols, acrylic acid and methacrylic acid, as well as their esters, polyester and polyamide resins, and also chlorinated rubber, natural and synthetic rubber, which may be chlorinated or cyclised, also reaction resins such as epoxy resins, polyurethane resins, unsaturated polyesters which may be converted into film-forming products of high molecular weight by adding hardeners.
The binders may be liquid or in the form of solutions. Solid coating compositions can be applied to objects by powder coating techniques. Other conventional basic components are typically tar, modifiers, dyes, inorganic or organic pigments, fillers and hardeners.
