Patent GB-773508-A (GB)
Title: A process for producing electrolyte-stable dispersions
IPC: C09K23/00
Filed: 1954-06-22
Abstract: A polyalkylene oxide wax, having a molecular weight above 1000, a phosphoric acid or anhydride thereof or a chloride of phosphorus, and an aliphatic, alicyclic or aliphatic-aromatic compound which contains at least 6 carbon atoms per molecule and contains an exchangeable hydrogen atom linked to oxygen, sulphur or nitrogen, are condensed at 60-170 DEG  C.  The product which is neutral or slightly acid may be neutralized before use.  Specified condensate components are (1) polyoxyalkylene waxes: polyoxyethylene wax of molecular weight 5000-10,000, and polyoxypropylene wax; (2) phosphorus-containing components: orthophosphoric acid, phosphorus pentoxide, trichloride and oxychloride; (3) exchangeable hydrogen-containing component: fatty, naphthene, cyclohexyl, alkylated cyclohexyl, and resin alcohols; alkyl phenols and alkyl naphthols with C3-C18 alkyl residues; the corresponding amines, mercaptans, carboxylic acids, amides and sulphonamides.  In the case of hydroxyl compounds, specified proportions of components (1), (2) and (3) are 1 : 1 : 1 up to 1 : 2 : 4.  In examples: (1) a polyoxyethylene is melted, phosphorus pentoxide and stearyl alcohol stirred in, the temperature and pressure adjusted to 120 DEG  C. and 11 mm. Hg respectively and the mixture heated for 8 hours; (2) an emulsifier prepared from polyoxyalkylene wax, phosphorus oxychloride and dodecyl alcohol is referred to; (3) a dispersant prepared from polyoxyalkylene wax, phosphorus oxychloride and dodecylbenzenesulphamide is referred to. Reference has been directed by the Comptroller to Specifications 689,724, [Group VIII], and 753,668, [Group III].ALSO:A condensation product of a polyalkylene oxide wax, having a molecular weight above 1000, a phosphoric acid or anhydride thereof or a chloride of phosphorus, and an aliphatic, alicyclic or aliphatic-aromatic compound which contains at least 6 carbon atoms per molecule and contains an exchangeable hydrogen atom linked to oxygen, sulphur or nitrogen is used as a dispersing agent for emulsions or dispersions. The product which is neutral or slightly acid may be neutralized before use.  Specified condensate components are (1) polyoxyalkylene waxes; polyoxyethylene wax of molecular weight 5,000-10,000, and polyoxypropylene wax (2) phosphorus containing components: orthophosphoric acid, phosphorus pentoxide, trichloride and oxychloride (3) exchangeable hydrogen-containing component; fatty, naphthene, cyclohexyl, alkylated cyclohexyl, and resin alcohols; alkyl phenols and alkyl naphthols with C3 - C18 alkyl residues; the corresponding amines, mercaptans, carboxylic acid, amides and sulphonamides.  Specified dispersed substances are: synthetic or natural resins, resin oils, oils, fats, waxes, and rubber; albumenous substances, cellulose derivatives, polyvinyl substances, polyesters, polyamides, organic and inorganic pigments, matting agents, weighting agents and fillers.  In examples, (1) a polyoxyethylene wax is melted, phosphorous pentoxide and stearyl alcohol stirred in, the temperature and pressure adjusted to 120 DEG C. and 11 m.m. Hg. respectively and the mixture heated for 8 hours.  An addition product of octadecanol and ethylene oxide, and the above material are dissolved in water and paraffin oil emulsified therein, (2) an emulsifier prepared from polyoxyalkylene wax, phosphorous oxychloride and dodecyl alcohol is mixed with spindle oil and sulphonated olein, and the paste mixed with a chrome tanning solution, (3) a dispersant prepared from polyoxyalkylene wax, phosphorous oxychloride and dodecylbenzenesulphamide is dissolved in water, and commercial chlorparaffins containing 30-60 per cent by weight of chlorine, and decalin are stirred in.  Chromic oxide is then added  Reference has been directed by the Comptroller to Specifications 689,724 [Group VIII] and 753,668.
