The catalyst may be for example an acid, a base or a phase transfer catalyst.
The known compounds are prepared in analogous manner.
The compounds of formula i are very suitable for improving the properties, especially the 35 corrosion-inhibiting properties in non-aqueous functional fluids.
The compounds of formula 1 are employed as corrosion inhibitors in nonaqueous functional fluids in amounts of 0.001 to 5% by weight, especially 0.05 to 3% by weight, based on the non-aqueous functional fluid.
The non-queous functional fluid may be a lubricating oil e.g. a natural or synthetic lubricating 40 oil; a refined petroleum product such as a fuel oil, diesel oil, kerosene, gasoline or aviation fuel; or a hydraulic fluid, e.g. a phosphate-based synthetic oil.
The lubricating oil may be a mineral oil, a synthetic oil or any mixture of such oils. Mineral oils are preferred and examples of these include paraffin oils, e.g. a mineral oil having a viscosity of 46 MM2/ s at 4WC;---150 Solvent Neutral-, a solvent refined neutral mineral oil having a viscosity of 32 MM2/ s at 4WC; and -Solvent brightstocks-, a high-boiling residue from the process of refining mineral oil, and having a viscosity of 46 MM2 /s at 4WC.
Synthetic lubricating oils which may be present are for example synthetic hydrocarbons such as polybutenes, alkyl benzenes and poly-alpha olefins as well as simple di-, tri- and tetraesters, complex esters and polyesters. Diesters are derived e.g. from carboxylic acid esters of the formula R5-0(0)C-alkylene-C(O)O-R4 wherein "alkylene" is a C2-Cl4alkylene residue and R4 and R5 are the same or different and each 55 is a C,-C,,,alkyl group.
Triesters which may be used as lubricating oil base-stocks are those derived from trimethylol propane and C,-C,,monocarboxylic acids or mixtures thereof, whereas suitable tetraesters include e.g. those derived from pentaerythritol and a C,-C,,,monocarboxylic acid or mixtures thereof.
Complex esters suitable for use as components of the compositions of the present invention 60 are e.g. those derived from monobasic acids, dibasic acids and polyhydric alcohols, for instance the complex ester derived from trimethylolpropane, caprylic acid and sebacic acid.
Suitable polyesters are e.g. those derived from a C4-C,,dicarboxylic acid and at least one aliphatic dihydricCl-Cl2alcohol, e.g. those derived from azelaic acid or sebacic acid and 2,2,4- trimethylhexane-1,6-diol.

(1) primary, secondary or tertiary aliphatic or cycloaliphatic amines and amine salts of organic 10 and inorganic acids, e.g. oil-soluble alkylammonium carboxylates; and (11) heterocyclic compounds, e.g.: substituted imidazolines and oxazolines.
c) phosphorus-containing compounds, e.g.:
amine salts of phosphoric acid partial esters d) sulfur-containing compounds, e.g.: barium dinonyl naphthalene sulfonates and calcium petroleum sulfonates.
Examples of viscosity-index improvers are:
polymethlacrylates, vinylpyrrolidone/methacrylate copolymers, polybutenes, olefin copolymers, styrene/acrylate copolymers.
Examples of pour-point depressants are:
polymethacrylates and alkylated naphthalene derivatives.
Examples of dispersing agents1surfactants are:
polybutenylsuccinic acid imides, polybutenylphosphonic acid derivatives, and basic Mg, Ca and Ba sulfonates and Mg, Ca and Ba phenolates.
Examples of anti-wear additives are: compounds containing sulfur and/or phosphorus and/or halogen, e.g.: sulfurised vegetable oils, zinc dialkyl dithiophosphates, tritolyl phosphate, chlorinated paraffins, alkyl disulfides and aryl disulfides.
The compounds of formula I are useful as additives in particular to lubricating systems, especially engine oils, in which they exhibit corrosion-inhibiting properties. Relative to known compounds having comparable properties, the compounds of formula I are advantageous in that they are phosphorus- and tin-free so that not even the after-combustion of the exhaust gases is impaired.
Example 1:
10.5 parts of diethanolamine are added dropwise on to 22.8 parts of tertnonylcarboxyglycidyl ether at WC and the resultant solution is stirred for 3 hours. The crude product is distilled to give 28.1 parts of N,Ndi(hydroxyethyi)-2-hydroxy-3-tert-nonylcarbonyloxypropylamine. Boiling point: 225'C/0.13 mb.
Example 2:
10.5 parts of diethanolamine are heated to WC and 27.1 parts of tertdodecyigiycidyl thioether are added dropwise. After completion of the addition, the mixture is stirred for 1 hour at 7WC. 3-tert-Dodecyithio-l[di(2-hydroxyethyi)amino]propan-2-ol is obtained as a yellow vis- cous liquid having refractive index n 20---1.4972 in a yield of 100% of theory.
D_ Example 3:
By following a procedure analogous to that of Example 2, 21 parts of diethanolamine are reacted with 45.4 parts of tert-nonylgiycidyl thioether to produce 3-tert- nonylthio-l-[di(2-hydroxy- ethyi)aminolpropan-2-ol as a yellow viscous liquid having refractive index n2bc-- 1.5008 in a yield 55 of 100% of theory.

The results are set out in Table 3 and are expressed as the concentration (ppm) of the product which will prevent any trace of rusting of the test spindle. In both A and B tests, the absence of additive causes severe rusting of the test spindle to occur.
