Definitions

• the present invention relates to a process for improving the wetting-out properties of alkaline lyes of at least 18 B. and to such improved lyes and is based on the use of naphthenic acids as such or in combination with emulsifying agents of non-phenolic character or with aminoor ether alcohols.
• the present invention resides on the observation that naphthenic acids can very well be used alone as wetting agents in concentrated alkaline lyes say from 18 B. upwards, if their molecular weight or their acid number is adapted to the concentration of the lye.
• concentrated alkaline lyes possessing excellent Wettingout power are prepared by adding thereto small quantities of selected fractions of naphthenic acids, whereby the selection is so made that th quotient acid number of the naphthenic acid fraction content in percent of alkali in the lye must be a number between and 25.
• This mathematical expression means that for lyes of lower concentration fractions of naphthenic acids with a low acid number are used, whereas for concentrated lyes naphthenic acids possessing a high acid number will be employed.
• acid number it is also possible to say molecular weight, as a low acid number of a fraction indicates high molecular naphthenic acids, and a high acid number indicates low molecular acids.
• the acid number is adapted to the concentration of the lye by following the above mathematical rule, the naphthenic acid fraction will generally be clearly soluble in the and penetrating action for raw cellulosic fibres.
• Such a lye will then be of great advantage for the treatment of cellulosic material, for instance for the mercerisation of raw unbowked cotton or the alkalisation of raw paper pulp in the manufacture of rayon.
• the acid number of naphthenic acids varies between 250 and 500 and if the above rule is followed, it will be clear that for sodium hydroxide lyes of 30 B. and upwards, naphthenic acid fractions possessing the acid number 380 and upr ups.
• wards will be preferably used.
• dilute lyes say of 22-26 B. fractions with the acid number of about 320-360 are suitable. If dilute lyes, say of 18-22" B., are used, then the corresponding acid number of the naphthenic acidfractions will be of 250-320.
• the wettingout power of naphthenic acids can be increased if the above quotient increases in value by adding t ereto a small amount of aminoor ether alcoho s.
• the activity of the naphthenic acids can be increased by adding theretma certain amount of emulsifying agents of a nonphenolic character.
• naphthenic acid fractions of low molecular weight are used in rather dilute alkaline lyes, they obtain the property of emulsifying therein substances like aminoor ether alcohols, which then increase the wettingout power of alkaline lyes.
• naphthenic acid fractions with the acid number 380 and upwards are used in lyes of say 22-28 B.
• ether alcohols saturated and unsaturated compounds of thealiphatic, cycloaliphatic, aralian ether linkage at least one aliphatic hydroxy group such as the ethers of glycol, glycerine and polyvalent alcohols
• the acetalsv derived from polyvalent alcohols and ketones or aldehydes can 5 be used.
• amino alcohols compounds containing one. or more nitrogen atoms and one or more oxalkyl groups in the molecule are suitable for improving the wetting-out properties of the fractions of naphthenic acids.
• derivatives which belong to the class of sulphonic acids of alkylated aromatic compounds, aliphatic and heterocyclic sulphonic acids with at least three carbon atoms in the molecule, the sulphuric esters of aliphatic alcohols with 2 to 12 carbon atoms possessing straight or ramified carbon chains, the sulphuric acid esters of etherand amino alcohols, aliphatic saturated or unsaturated monocarboxylic acids with 3 to 12 carbon atoms and with straight ramified carbon chains, which chains can eventually contain oxygen bridges; such cids are for example isobutyric acid, isovaleri nic acid, isocapronic acid, isobutylacetic acid, isoamyl acetic acid, methylisobutyl acetic acid, methylisoamyl acetic acid, ethylpropyl acetic acid, dipropyl acetic acid, 1:3- di
• Still another object of the present invention are the alkaline lyes of 18 B. and more containing suitable fractions of naph'thenic acidin mixture with aminoor ether alcohols or in mixture with emulsifying agents of an'acid character and the process of treating cellulosic material, especially the mercerizing process of cellulosic fibres with the said lyes.
• One object of the present invention is therefore a process for improving the wetting-out power of. alkaline lyes of a concentration superior to 18 B. by adding thereto fractions of naphthenic acid selected in such a manner that the quotient acid number of the naphflienic acid fraction content in percent of alkali in the lye is a number between and 25.
• Another object of the. present invention is. a process for improving the wetting-out action of alkaline lyes by adding to concentrated lyes naphthenic acid fractions with a high acid numher, and to more dilute lyes,-fractions with a lower acid number.
• Still another object of the presentinvention are the improved alkaline solutions of 18 B. and more containing suitable fractions of naphthenic acids.
• Still another object of .the present invention is the process for improving the wetting-out action of alkaline lyes by adding thereto mixtures of Column 1 of this table gives the boiling point of the naphthenic acid fraction.
• the following second table shows the action. in lyes of diiferent concentration, of mixtures of a naphthenic acid fraction of the acid number 384 and boiling point 130-140" C. with other compounds increasing its wetting-out properties in comparison to the action of the naphthenic acid fraction "itself.
• Table III shows the action of the same naphthenic acid fraction as above in mixture with the acetals obtained from glycerine and technical methylcyclohexanones.
• Lyes possessing excellent wetting-out power may further be prepared by using following mixtures:
• a process for the alkaline treatment of cellulosic material comprising subjecting the cellulosic material to a treatment with a phenol free alkaline lye of 18 B. and more containing a wetting capacity increasing agent consisting of such fractions of naphthenic acids that the quotient acid number of the naphthenic acid fraction content in percent of the alkali in the lye is a number between 15-25.
• a process for the alkaline treatment of cellulosic material comprising subjecting the cellulosic material to a treatmentwith phenolfree' alkaline lyes of 30 B. and more, containa wetting capacity increasing agent consisting of which is 3 menace cellulosic material to a treatment with phenoliree alkaline lyes of 26-30 Ba, containing a wetting capacity increasing agent consisting of fractions of gaphthenic acids, the acid number 0-380 and the quotient acid number of the naphthenic acid fraction content in percent of the alkali in the lye is a number between 15-25. 8.
• a process for the alkaline treatment of cellulosic material comprising subjecting the c'ellulosic material-to a treatment with phenolfree alkaline lyes of 18-26 B., containing a wetting capacity increasing agent consisting of fractions ⁇ of naphthenic acids, the acid number of which is 250-360 and the quotient is a number between 15-25.
