Definitions
- oils have a density between 0.890 and 0.935, most generally 0.910 to 0.925. They distil from 50-220" C. 80-90% passingon the average from l-130 C. to 205-210 C. They are rich in ketonic products (30-45% calculated as acetone) and allyl compounds (IO-30% calculated as allylalcohol) hydes, diketones, alcohols, hydrocarbons, furane and cyclopentane derivatives, amines, and other products which are unknown or not identified at present but which contribute for their part to tliil: special and characteristic properties of these 0 According to the present invention the unexpected'discovery has been made that these oils and all the fractions which are still very complex and which can be separated therefrom in one way or another exhibit inhibitory properties towards the attack on metals by acids or strongly dissociatedsadts.
- the residual oil about 0.9 part by volume may be extracted again by agitation in the cold with an equal volume of acid as described above and give a new quantity of extract only half as rich as the above extract.
- a practically deodorized extract may be ob tained by eliminating from the above extracts by distillation with a column, a first fraction of 10 which entrains the most volatile and strongly odoriferous constituents.
- a metal treating bath comprising a diluted mineral acid and as an inhibitor product preventing the attack of the 'metal itself a low proportion of crude wood spirit oils arising from the carbonization of wood.
- a metal pickling bath comprising a diluted mineral acid and as an inhibitor product preventing the attack of the metal itself a low proportion of crude wood spirit oils arising from carbonization of wood.
- A. metal scaling bath comprising a diluted mineral acid and as an inhibitor product preventing the attack of the metal itself a low proportion of crude wood spirit-oils arising from carbonization or wood.
- a metal treating bath comprising a diluted mineral acid and as an inhibitor product preventing the attack of the metal itself a low proportion of an aqueous extract of wood spirit oils.
