Definitions
- the invention relates to a liquid composition and to a process for the preparation of such a liquid composition.
- the invention specifically relates to a liquid composition comprising
- composition according to the invention is an oil-containing clear and liquid solution of an alkylated xylenesulphonic acid salt, which is substantially anhydrous as herein defined.
- the composition has an excellent storage stability and a suitable viscosity. It may be used as a protective fluid in metal-working industry. It may also be used as a quenching oil in metal processing. It shows no phase separation nor crystallization at zero degree C.
- compositions are those wherein an alkylated xylenesulphonic acid salt is an ortho-xylenesulphonic acid salt of the formula wherein M is an alkali metal or ammonium and A is a C 8 -C 30 alkyl group, preferably a C 12 -C 2 o alkyl group.
- the long chain-alkyl group is bound to the aromatic ring from its 2-position to its mid-position.
- the glycol is polyethylene glycol or polypropylene glycol.
- Preferred molecular weights range from 200 to 1200, more preferred from 300 to 1000.
- compositions comprise 50 to 65 percent by weight of alkylated xylenesulphonic acid salt; 5 to 20 percent by weight of glycol; less than one percent by weight of water and the balance being an oil, preferably a naphthenic oil or paraffinic oil.
- compositions according to the invention may be prepared by neutralizing an alkylated xylenesulphonic acid in the presence of an aromatic, paraffinic or naphthenic oil, subsequently adding a glycol to the neutralized reaction mixture and distilling off the water to a level of less than one percent by weight. The distillation is carried out at a temperature of 80 ° C to 100 ° c.
- compositions according to the invention are the C l 3 , C, 4-alkyl ortho-xylene sulphonic acid salt and the C 16 -C 18 -alkyl ortho-xylene sulphonic acid salt, specifically the sodium salt.
- alkyl ortho-xylene sulphonates in a concentration of about 60 percent by weight of active material in an oil, containing also less than 10 percent by weight of water (without a glycol).
- Said composition is generally a rigid gel and with only containing water in a small range of 4.2 to 4.8 percent by weight, the composition is liquid.
- Low water content formulations of this type (without glycol) are generally solids.
- the water content is replaced by polyglycol. After the glycol has been added to the formulation, the water is distilled off. This process may be facilitated by introducing in the neutralization vessel nitrogen or air.
- alkylated ortho-xylene sulphonic acids having the chemical structure wherein A represents C 16 - and C 18 -alkyl (average mol. weight 425) were neutralized with 124.6 g of aqueous 47% by weight of sodium hydroxide solution in 257.7 g of paraffinic oil.
- the formulation comprised 60% by weight of active matter, 10% by weight of water and had a kinematic viscosity of 340 mm 2 /s at 60 ° c and a solidification point of 30 °C to 40 °c.
- the water content was 0.6 percent by weight on the total composition of 1000 g.
- This product had a kinematic viscosity of 1780 mm 2 /s at 60 °C, and remained a liquid even below 0 °C without crystallization.
- alkylated ortho-xylene sulphonic acids having the chemical structure wherein A is C 13 - and C14-alkyl (average mol. weight 380) were neutralized with 134.8 g of aqueous 47% by weight of sodium hydroxide solution in 256.0 g of paraffinic oil.
- This formulation had a kinematic viscosity of 190 mm 2 /s and a solidification point of 30 °C to 40 °c.
- the water content was 0.5 percent by weight on the total composition of 1000 g.
- This product had a kinematic viscosity of 4950 mm 2 /s, and remained a liquid even at 0 °C.
- Example 1 The process of Example 1 was repeated, whereby instead of a paraffinic oil a naphthenic oil was used.
- the amounts of the components were the same as those used in the process of Example 1.
- the water content was 0.6 percent by weight on the total composition of 1000 g. This product was just yet a liquid at 0 °C without any crystallization.
- the naphthenic oil had the following properties:
- the paraffinic oil had the following properties:
