Patent number: 4402847Abstract: Compositions and method of using said compositions for inhibiting mineral scale and the corrosion of high lead solder and the cavitation-erosion corrosion of aluminum in aqueous systems are disclosed. Unexpectedly, a mixture of a siloxane-silicate copolymer with an azole is effective in reducing the corrosion of high lead solder and aluminum, particularly the cavitation-erosion corrosion of aluminum in contact with aqueous liquids, such as aqueous alcohol solutions used as heat transfer media. Antifreeze concentrates and a process for inhibiting corrosion are also disclosed.Type: GrantFiled: May 19, 1982Date of Patent: September 6, 1983Assignee: BASF Wyandotte CorporationInventors: Joe C.

Patent number: 4389371Abstract: Corrosion inhibited alcohol compositions can be prepared which are suitable for use as anti-freeze compositions in the cooling systems of internal combustion engines. The alcohol is selected from at least one of the group consisting of methanol, ethanol, propanol, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol and glycerol. The corrosion inhibitor comprises an effective amount of a conventional corrosion inhibitor selected from the group consisting of the alkali metal carbonates, borax, the alkali metal dichromates, the alkali metal silicates, phosphorous acid, phosphoric acid, an alkali metal tungstate, benzotriazole, tolyltriazole, an alkali metal salt of benzoic or toluic acid, an alkali metal salt of a phenol, an alkanolamine and an organo-silicone compound in addition to an alkanolamine phosphate and a heterocyclic nitrogen-containing compound. The phosphate is the reaction product of an alkanolamine and phosphoric acid.Type: GrantFiled: July 8, 1981Date of Patent: June 21, 1983Assignee: BASF Wyandotte CorporationInventors: Joe C.

Patent number: 4292190Abstract: Tertiary, cyclic, bridgehead amines are disclosed as useful corrosion inhibitors for metals in contact with aqueous alkaline liquids. The disclosed amines have been found to be strongly resistant to thermal decomposition, to chemical attack, and to nitrosation. The use of these corrosion inhibitors is particularly desirable in aqueous alcohol compositions useful as a heat exchange liquid in the cooling systems of an internal combustion engine wherein said aqueous solutions are ethylene glycol-based compositions. The disclosed amines are useful under alkaline conditions alone or in combination with conventional corrosion inhibitors such as water-soluble metal salts of tolyltriazole and phosphoric acid, alkali metal nitrites and nitrates, and alkali metal phosphates.Type: GrantFiled: April 21, 1980Date of Patent: September 29, 1981Assignee: BASF Wyandotte CorporationInventors: Pauls Davis, Jerrold F. Maxwell, Joe C. Wilson

Patent number: 4241012Abstract: This invention relates to single-phase antifreeze or coolant concentrates comprising (1) an alcohol, (2) at least one of an amino siloxane, an amino silane or both an amino siloxane and an amino silane and a siloxane of the formula: ##EQU1## wherein R.sup.6 is a monovalent hydrocarbon group and e has a value of from 1 to 3, and (3) a hydroxybenzoic acid basic pH buffer preferably comprising para or ortho hydroxybenzoic acid or mixtures thereof. The concentrates are preferably used, upon dilution with about 30 to about 90 percent by weight of water based upon the weight of said concentrate, as antifreeze compositions for internal combustion engines. The alcohol is preferably ethylene glycol. The coolant compositions are effective in providing protection against corrosion of all metals and alloys used in industrial heat exchangers and are especially effective in inhibiting the corrosion of aluminum internal combustion engine and radiator components.Type: GrantFiled: September 24, 1979Date of Patent: December 23, 1980Assignee: BASF Wyandotte CorporationInventors: Stanley T.
