Abstract: Monomeric aliphatic monohydric alcohols containing at least eight carbon atoms are etherified with di- or tri-ethyleneglycol or by means of the requisite quantity of ethylene oxide or ethylenehalohydrin.  The resulting ethers are stated to be emulsifying agents and they may also be used for oiling wool. They may be used in admixture with soaps, turkey red oils or other sulphonated compounds, e.g., sulphuric esters of the higher alcohols, palmitic and stearic sulphonic acids, oleic-N-methyl tauride and alkylated aromatic sulphonic acids, glue, gelatine, gum arabic and solvents, e.g., carbon tetrachloride, cyclohexanol, cyclohexanone and cresyl or xylyl ethers of ethyleneglycol.  In examples (1) dodecyl alcohol is etherified with ethylene-oxide and the product mixed with the sodium salt of the sulphuric ester of hydroxy stearic acid; an emulsifying agent or spot removing agent is obtained: (2) octodecyl alcohol is etherified with ethylene p  oxide and the resulting mono octodecyl ether of diethylene glycol possibly further etherified with dodecylalcohol; oleic-N-methyl-tauride or the sulphuric ester of hydroxystearic acid is mixed with either product, a stable emulsion being obtained: (3) dodecyl alcohol is etherified with ethylene oxide and the product mixed with paraffin oil, paraffin wax, petroleum jelly and water; (4) oleylalcohol is etherified with ethylene oxide and the resulting monooleylether of triethylene glycol used to prepare aqueous emulsions of oils or fats, such as olive oil, or mineral lubricating oils.  The emulsification of ester bearing waxes and the higher alcohols is also mentioned.ALSO:Monomeric aliphatic monohydric alcohols containing at least eight carbon atoms are etherified with di- or triethylene glycol, or by means of the requisite quantity of ethylene oxide or ethylene halogenhydrin.  The products are stated to be wetting, emulsifying, penetrating and softening agents and may be used in the textile, leather, paper, lacquer, pharmaceutical and cosmetic industries.  Their use in the manufacture of insecticides, in greasing wool and in washing, bucking, fulling and dyeing baths is referred to.  They may be used in admixture with soaps, turkey red oils or other sulphonated compounds of high molecular weight such as sulphuric esters of the higher alcohols, palmitic and stearic sulphonic acids, oleic-N-methyl tauride and alkylated aromatic sulphonic acids, glue, gelatine, gum arabic and solvents such as carbontetrachloride, cyclohexanol, cyclohexanone, and cresyl or xylyl ethers of ethylene glycol. Dispersions of fats, paraffin and other waxes, higher alcohols and mineral oils are readily obtained by means of the ethers and the dispersions so prepared may be used as pest destroying agents.  To facilitate the etherification of the higher alcohols, the condensation catalysts employed in the process of Specification 380,431, e.g., surface active catalysts, strongly acid or alkaline substances may be used.  In examples: (1) dodecyl alcohol is etherified with ethylene oxide and the product is mixed with the sodium salt of the sulphuric ester of hydroxystearic acid; the resulting oil may be used for scouring wool, brightening textiles and for emulsifying; (2) octodecyl alcohol is etherified with ethylene oxide and the resulting mono octodecyl ether of diethyleneglycol possibly further etherified with dodecyl alcohol; oleic-N-methyltauride or the sulphuric ester of hydroxystearic acid is mixed with either product, a stable emulsion, which may be used for softening viscose or acetate, cupro-ammonium or other artificial silk being obtained; (3) dodecyl alcohol is etherified with ethylene oxide and the product mixed with paraffin oil, paraffin wax, petroleum jelly and water to obtain a paste suitable as a skin cream; (4) oleyl alcohol is etherified with ethylene oxide and the product used to prepare a dressing by adding octodecylstearate, octodecyl alcohol, Marseilles soap and water; (5) oleyl alcohol is etherified with ethylene oxide and the product mixed with a solid polymerisation product of ethylene oxide (cf. Specification 346,550); (6) dodecyl or oleyl alcohol is etherified with ethylene oxide and a printing paste for wool muslin prepared from the product by adding Acid violet 4 BC, glycerine, British gum and ammonium oxalate; (7) oleyl alcohol is etherified with ethylene oxide and the resulting mono oleyl ether of triethylene glycol used to prepare aqueous emulsions of oils or fats, such as olive oil or mineral lubricating oils, to which fungicidal or insecticidal substances may be added. Specifications 341,053, 343,899, 343,901, and 360,493 also are referred to.ALSO:Ethers which are derived from monomeric aliphatic monohydric alcohols containing at least eight carbon atoms and di- or tri-ethylene glycol are used in the preparation of insecticides. In an example, fungicidal and insecticidal substances may be added to an aqueous emulsion containing mono oleyl ether of ethylene glycol and an oil or fat such as olive oil or lubricating oil. Pest destroying agents may also be prepared by emulsifying fats, waxes, the higher alcohols, paraffin waxes or mineral oils with the said ethers.
