## Abstract

The present invention relates to a lubricating composition for forging in the form of a powder or a compacted powder including: one or more dicarboxylic acid(s) chosen among adipic acid, phthalic acid, isophthalic acid, terephthalic acid, sebacic acid, succinic acid and suberic acid; and one or more base(s) chosen among sodium carbonate, sodium bicarbonate, potassium carbonate and potassium bicarbonate, the dicarboxylic acid(s)/base(s) molar ratio ranging between 0.8 and 1.2.

## Claims

### Claim 1

A lubricating composition for forging in the form of a powder or a compacted powder comprising:
one or more dicarboxylic acid(s) chosen among adipic acid, phthalic acid, isophthalic acid, terephthalic acid, sebacic acid, succinic acid and suberic acid, and
one or more base(s) chosen among sodium carbonate, sodium bicarbonate, potassium carbonate and potassium bicarbonate,
the dicarboxylic acid(s)/base(s) molar ratio ranging between 0.8 and 1.2.

### Claim 2 (depends on 1)

The composition according to claim 1, wherein the composition comprises from 30% to 100% by mass of the total composition of the combination of the dicarboxylic acid(s) and the base(s).

### Claim 3 (depends on 1)

The composition according to claim 1, wherein the carboxylic acid(s) comprises adipic acid and the base(s) comprises sodium carbonate.

### Claim 4 (depends on 1)

The composition according to claim 1, wherein the carboxylic acid(s) comprise adipic acid, and the base(s) comprise sodium carbonate and potassium carbonate.

### Claim 5 (depends on 1)

The composition according to claim 1, wherein the carboxylic acid(s) comprise adipic acid and isophthalic acid and the base(s) comprises sodium carbonate.

### Claim 6 (depends on 1)

The composition according to claim 1, further comprising one or more additive(s) chosen among colorants, gelling or thickening agents, wetting and/or spreading agents, mineral fillers or binding agents, and fillers or lubricant additives or extreme pressure or anti-wear.

### Claim 7 (depends on 1)

The composition according to claim 1 is in the form of a compacted powder.

### Claim 8 (depends on 7)

The composition according to claim 7, further comprising one or more additive(s) chosen among cohesion agents, disintegrating agents, and tableting aid agents.

### Claim 9 (depends on 1)

A method for preparing a lubricating solution for forging comprising the putting into solution of a composition according to claim 1 in an industrial or softened water bath, possibly under stirring.
