Abstract

The present invention relates to a wood preservative comprising either (1) at least one of (a) ammonium monofluorophosphate and/or diammonium monofluorophosphate of the general formula (R.sub.1 R.sub.2 R.sub.3 R.sub.4 N)R.sub.5 PO.sub.3 F in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are identical or different and each denotes a straight-chain, branched or cyclic, saturated or unsaturated alkyl, aralkyl, alkyaryl or aryl radical, either unsubstituted or substituted by an alkyl, alkoxy or a hydroxyl group, up to three of the four R.sub.1 -R.sub.4 can be hydrogen or can together form an alkylene bridge, R.sub.5 is a hydrogen atom or a R.sub.6 R.sub.7 R.sub.8 R.sub.9 N group in which R.sub.6, R.sub.7, R.sub.8 and R.sub.9, respectively, have the same meanings as R.sub.1, R.sub.2, R.sub.3 and R.sub.4, respectively, and (b) a mixture of a salt of monofluorophosphoric acid and at least one ammonium salts of the general formula R.sub.1 R.sub.2 R.sub.3 R.sub.4 NX in which X is an acid radical, or (2) a mixture of (a) and/or (b) and (c) an alkali metal monofluorophosphate or an ammonium monofluorophosphate of the general formula M.sub.2 PO.sub.3 F and/or MHPO.sub.3 F, in which M is sodium, potassium or ammonium. The present invention also relates to a coating agent comprising an ammonium monofluorophosphate as above and components (d) that comprises at least one of a binder, a fixing agent and a plasticizer, and (e) a diluent, and to methods of producing and using such agents.
