Definitions

  • the present invention relates to the reclaiming and utilization of waste wax' paper. More particularly the present invention relates tothe utilization of wax cuttings and the like known in the art as wax broke for the manufacture of any other type of paper either alone or in admixture with additional wood fiberor other forms of paper.
  • a second object of the present invention is to provide a novel process which includes fixing the wax derived from wax broke directly on the fibers in such a manner that no wax deposits are formed in the paper making machinery or wax spots in the finished sheet.
  • a suitable quantity of wax broke is charged into a beater or other paper making apparatus capable of disintegrating the same. Thereafter the beater is heated to a temperature sufflcient to melt the wax.
  • the heater is brought to a temperature above this point, such as ap-' proximately -160 F., by the use of steam or by other heating means.
  • a cationic surface active material of the type hereinafter to she described is added to the proportion of at least 3% by weight of the wax.
  • the cationic sub.- stance apparently fixes the residual wax on the fibers and permits the use of the so-treated broke in paper manufacture in the usual manner.
  • the cationic surface active agents used in accordance with the present invention include cer.. tain amino-amides, glyoxalidines cyclized from those amino-amides, and the solubilized derivatives of either.
  • the amino-amides may best be described by the general formula:
  • R represents an aliphatic chain containing from 7 to 23 carbon atoms
  • R denotes a substituent selected from the group consisting of hydrogen and alkylol groups containing 1 to 3 carbons
  • n is a number selected from the group consisting of 2 and 3 when R stands for hydrogen and n is a number selected from the group consisting ofl, 2 and 3 when R represents an alkylol radical.
  • Glyoxalidines may be formed from amino-amides of the above formula by internal condensation wherein the carboxyl carbon assault atom of the amide group is linked to the nitrogen atom of the nearest amino group in the molecule. This glyoxalidine ring formation occurs when the oxygen and hydrogen atoms of the amido group combine with a hydrogen.
  • compounds corresponding to soluble acid salts or alkylated derivatives of the above type of compound may be used. These may be produced by treating a compound of the general formula above described with an aliphatic monocarboxyiic acid of from 1 to 3 carbon atoms such as acetic, formic, glycolic, etc. or with a suitable ester of a mineral acid, as, for example, diethyl sulfate, triethyl phosphate, ethyl iodide, etc.
  • the resultant solubilized compounds may then be illustrated by the general formula;
  • R R and n have the values assigned of the respective residues of said acid and said ester; and where the formula also encompasses the same derivatives of glyoxalidines produced from the amino-amides prior to addition of the R and Z radicals by linking the carboxyl carbon atom with thenitrogen atom of the nearest amino group accompanied by liberation of a molecular proportion of water.
  • a suitable fat or fatty acid is reacted with a polyalkylene polyamine compound in order to form an amino-amide, or in the alternative, the fatty acid or fat is reacted with an alkylene alkylol polyamine or a polyalkylene alkylol polyamine compound.
  • the amino-amide may be heated to a relatively high temperature to drive oil water in order to form a cyclic compound.
  • the amino-amide, or the cyclic glyoxalidine compound equivalent to the amino-amide may then be treated with an agent rendering the compound water soluble, such as a suitable ester of a mineral acid, for example, diethyl sulphate, triethyl phosphate, ethyl iodide, or an aliphatic monocarboxylic acid of from 1 to 3 carbon atoms such as acetic, formic, glycolic, etc. or the amide or glyoxalidine may be added first to the paper fibers and wax and thereafter the acid.
  • an agent rendering the compound water soluble such as a suitable ester of a mineral acid, for example, diethyl sulphate, triethyl phosphate, ethyl iodide, or an aliphatic monocarboxylic acid of from 1 to 3 carbon atoms such as acetic, formic, glycolic, etc. or the amide or glyoxalidine may be added first to the
  • temperatures in the neighborhood of 200 C. or from 150 to 210 C. are utilized for the amidification, and in the event the cyclic compound is desired, temperatures in the neighborhood of 300 C. are used.
  • Various polyalkylene polyamine, alkylene alkylol polyamine or polyalkylene alkylol polyamine compounds having from 2 to 4 amino groups may be used as, for example, diethylene triamine, ethanol ethylene diamine, ethanol diethylene triamine, triethylene tetramine, etc.
  • Almost any fatty acid or fatty acid glyceride having from 8 to 24 carbon atoms in the chain may be utilized as the fatty acid portion of the compound.
  • olelc acid, ricinoleic acid, lauric acid, stearic acid, palmitic acid, etc. are examples of the fatty acids which may be utilized in preparing the amino-amide compound.
  • Example I 74.8 parts by weight of hydrogenated soybean oil and 25.2 parts of ethanol ethylene diamine were condensed in a closed vessel at 150 C. for from 6 to 8 hours.
  • the product was believed to consist largely of an amino-amide having the following formula:
  • Example II 78.3 parts by weight of peanut oil and 27.5 parts by weight of diethylene triamine were heated together to a temperature of about C. in a closed vessel and held at this temperature for about 6 to 8 hours. Thereafter the amino-amide was added to wax broke in a beater as set forth in Example I. The only difference in the procedure being that after the amino-amide was added to the wax broke and water at 140 F. and beating continued for about 30 minutes, sufilcient acetic acid to bring the pH of the slurry from pH 8 to pH 6 was added and the slurry was again beaten for about 30 minutes. Sheets made from this slurry were also entirely satisfactory and no wax deposits in the beater were observed.
  • Example III 78.3 parts by weight of peanut oil and 27.5 parts by weight of diethylene triamine were heated together to a temperature of between and C. and held at this temperature for 20 minutes. Thereafter the reaction mixture was rapidly heated to 300 C. and the evolved water was collected ina moisture trap. when 5.8 parts of aqueous condensate were collected, the heat washut off and the product allowed to cool.
  • the resultant product was believed to have the followins formula:
  • R represents an aliphatic chain containing from 7 to 23 carbon atoms
  • R denotes a sub- 1 stituent selected from the group consisting of hydrogen and alkylol groups containing 1 to 3 carbon atoms
  • n is a number selected from the group consisting of 2 and 3 when R stands for hydrogen and n is a number selected from the group consisting'of 1, 2 and 3 when R represents an alkylol radical
  • R denotes a substituent selected from the group consisting respectively of hydrogen, when R-"Z is a 1 to 3 carbon aliphatic monocarboxylic acid, and an aliphatic alkyl group of from 1 to 3 carbon atoms
  • R 2 is an ester of a mineral acid with a 1 to 3 carbon aliphatic alcohol
  • Z is selected from the group consisting of the respective residues of said acid and said ester.
  • a process for reciaiming wax paper broke consisting of forming a suspension in water of the fibers of the waxbroke by disintegrating the broke in water heated to a temperature sufliciently high to melt the wax, and fixing the wax on the fibers by adding a cationic surface active substance to the fiber and wax suspension and thereafter adding an aliphatic rnonocarboxylic acid containing from 1 to 3 carbon atoms per molecule to the suspension to reduce the pH value to approximately 6, said cationic substance being selected from the group consisting of aminoamides having the general formula:
  • R represents an aliphatic chain containing from 7 to 23 carbon atoms
  • R denotes a substituent selected from the group consisting of hydrogen and alkylol groups containing 1 to 3 carbon atoms
  • n is a number selected from the group consisting of 2 and 3 when R stands for hydrogen and n is a number selected from the group consisting of 1, 2 and 3 when 1'1. represents an alkylol radical.
  • a process for reclaiming wax paper broke consisting of forming a suspension in water of the fibers of the wax paper broke by disintegrating the broke in water heated to a tern perature sumciently high to melt the wax, and fixing the wax on the fibers by adding the acetic acid solubilized derivative of ethanol amino ethylene stearamide to the suspension.
  • a process for reclaiming wax paper broke consisting of. forming a suspension in water of the fibers of the wax paper broke by disintegrating the broke in water heated to a temperature sufiiciently high to melt the wax, and fixing the wax on the fibers by adding ethanol amino ethylene stearamide to the suspension and thereafter adding acetic acid to the suspension.
