Definitions
- a corrosion inhibited alcohol/water antifreeze contains mercaptothiazoline together with an alkali metal salt of tetraboric acid and alkali metal carbonate or hydroxide in the molecular ratio of 1:2-4.
- the composition also contains an alkali metal silicate.
- This invent-ion relates to an inhibited antifreeze composition which is particularly suitable for addition to the cooling water in motor car radiators.
- Radiators of motor vehicles must be filled in winter with liquids which are not subject to the formation of ice crystals at temperatures below 0 C.
- Various alcohols may be mixed with the radiator water for this purpose but the most commonly used are glycerol and, particularly, ethylene glycol.
- glycerol and, particularly, ethylene glycol are also incorporated for the purpose of reducing corrosive tendencies of the final composition.
- These additives are often mixed with the antifreeze component and the resulting mixture is usually known as an inhibited antifreeze.
- the radiator system of an engine often contains a variety of different metals and it is clearly important that there shall be a low corrosive tendency in respect of all the metals present in the radiator system. It is important to realise that low corrosion rates may be even more important in the case of metals which form only a small proportion of the radiator system than in the case of metals which form the bulk of the construction. Thus, for example, solder, aluminium and bearing metals have to perform an important function and relatively small amounts of corrosion on these materials may be of greater significance than much greater corrosion in respect of the main metal of construction, e.g. cast iron or steel. Thus it is an object of the present invention to reduce the corrosive tendency of antifreezes in respect of many metals which are likely to be found in a radiator system.
- an inhibited antifreeze suitable for use in water-based radiator liquids, consists of:
- component (d) the molecular ratio of component (d) to component (e) being 122-4.
- component (e) is sodium carbonate the preferred molecular ratio is 1:3-3.5 and when component (2) is sodium hydroxide the preferred molecular ratio is 122.0- 3.0.
- benzarnide and/or phthalimide may be incorporated as additional ingredients.
- a particularly suitable inhibited antifreeze composition according to the invention consists of:
- Borax 0.5-5.0 Sodium carbonate 0.28-5.6
- Benzamide and/or phthalimide 0-0.5
- the same molecular ratio of borax to sodium carbonate applies as in the previous case since there is one molecule of anhydrous sodium bonate contained in .one molecule of borax.
- the quantity of water should be sutficient to maintain the components in solution; in effect this means that the quantity of water is controlled by the quantity of sodium carbonate.
- compositions I-VI Six compositions according to the invention will now be described by Way of example; these are identified as compositions I-VI. These compositions according to the invention will be compared with four other compositions illustrating borate-carbonate ratios outside the range of our invention; these comparative compositions are hereinafter identified as Cl-4. The specification also includes information on prior art compositions and these are designated as P1-9.

- the organic acids in Composition P5 were weak unsat- 45 urated acids (or their alkali metal salts) having a molecular weight of 300-350.
- compositions had the following formulations:
- compositions described above are normally diluted with l-2 parts by volume of water according to the lowest temperature expected. Tests were carried out on the corrosiveness of the various compositions to a variety of different metals and in these tests the compositions were diluted with two parts by volume of Water (i.e., the test solution consisted of one-third composition Triethanolamine phosphate 1.0 and two-th1rds water). The test results are given in Sodium mercaptobenzothiazole 0.3 Table 3.
- Figures indicate weight change in rug/cm. Indicates gain. Indicates loss.
- compositions P4, P5 and P9 give results of +0.26, +0.70 and +0.30 respectively.
- the worst result of the compositions according to the invention was given by composition IV with a figure of 0.12.
- P4 gave the best solder result but it had an aluminum result of +0.5.
- This figure also compares unfavourably with the worst aluminum figure according to our invention, namely 0.35. This further illustrates the superiority of the compositions according to our invention in reducing the tendency to corrosion in respect of all the metals used in the test.
- compositions according to our invention display an improvement over the comparative compositions illustrated above. It is however, interesting to note that compositions I, II and III (which contain mercaptothiazoline) gave even better results than those given by Compositions IV, V and VI (which contain mercaptobenzothiazole).
- Component ((2) will tend to form salts with the cation present in the antifreez solution. If desired component (c) may 'be added in the form of a salt, e.g. the sodium salt.
- a salt e.g. the sodium salt.
- An inhibited antifreeze composition suitable for use in water-based radiator liquids, and consisting essentially of the following ingredients:
- An alkali metal compound selected from the group consisting of sodium carbonate, sodium hydroxide, potassium carbonate and potassium hydroxide 0.28-5.6 Water 1.5-30 A water-miscible alcohol selected from the group of ethylene glycol and glycerol, q.s. to make 100%.
- the molecular ratio of the sodium tetraborate to the alkali metal compound being 132-4.
- composition in accordance with claim 1 which further includes up to 0.5 by weight of a compound selected from the group consisting of benzamide, phthalimide and mixtures thereof.
- An inhibited antifreeze, suitable for use in Waterbased radiator liquids which consists of:
- the molecular ratio of sodium tetraborate to sodium carbonate being 1:3-3.5 and the quantity of water being at least sufiicient to maintain the other components in solution.
