Title: Spin bath additives
IPC: D01F2/10
Filed: 1955-03-21
Abstract: Additives for spinning baths comprise the products obtained by acylating one mol. of a di- or poly-amine H(NHR)xNH2 with 0.2x to x mols. of tall oil or rosin acids and then reacting the product with more than sufficient alkylene oxide to condense with all the remaining replaceable hydrogen atoms; R is C2-C6 alkylene and x is 1-6.  Preferred products are those from ethylene diamine, diethylene triamine, &c., and ethylene oxide, using 4-40 mols. of the latter. The baths may also contain a condensation product of at least one mol. (preferably 3-15 mols.) of an alkylene oxide of 2 or 3 carbon atoms with a primary or secondary aliphatic or alicyclic amine of at least 8 carbon atoms (many specified); such product may be used in a proportion of 0.02-2 parts per part of the above acylated compound. The baths may be used in the manufacture of extruded fibres, filaments and foils of cellulosic compositions (especially cuprammonium and xanthate) and proteins (e.g. casein, zein and albumen) at temperatures up to 80 DEG  C.  Examples are given of spinning baths for viscose rayon containing the above products and also sulphuric acid, sodium sulphate and zinc sulphate.  The acylated products may also be used as additives to plasticisers and modifiers for vinyl plastics, alkyd resins, phenol-formaldehyde resins and other polymeric-type plastic materials.ALSO:Products suitable as spin bath additives are made by acylating one mol. of a di- or polyamine H(NHR)#cNH2 with 0.2#c to #c mols. of tall oil or rosin acids and then reacting the product with more than sufficient alkylene oxide to condense with all the remaining replaceable hydrogen atoms; R is C2-C6 alkylene and #c is 1-6.  Preferred amounts are 0.5-2 mols. of acid and 4-40 mols. of alkylene oxide per mol. of amine.  In the examples the amine is ethylene diamine, or a mixture of diethylene triamine and triethylene tetramine and the alkylene oxide is ethylene or propylene oxide.  Other compounds that may be used are propylene, trimethylene, tetramethylene, pentamethylene, hexamethylene and isobutylene diamines and the corresponding polyamines; these may be crude mixtures obtained by reacting ammonia with alkylene dihalides; butylene oxide is also specified.  Specification 415,718, [Group IV], is referred to.ALSO:Products obtained by acylating one mol of a di- or poly-amine H(NHR)xNH2 with 0.2x to x mols of tall oil or rosin acids and then reacting the product with more than sufficient alkylene oxide to condense with all the remaining replaceable hydrogen atoms are surface-active and are used as wetting agents for improving the absorptive power of fibrous bodies, in fulling and mordanting processes and as rewetting, dispersing, penetrating, softening and anti-static agents.  In the formula R is an alkylene radical of 2-6 carbon atoms and x is 1-6. Specification 415,718 [Group IV] is referred to.ALSO:Products obtained by acylating one mol of a di- or poly-amine H(NHR)xNH2 with 0.2x to x mols of tall oil or rosin acids and then reacting the product with more than sufficient alkylene oxide to condense with all the remaining replaceable hydrogen atoms are surface-active and are used (1) for converting water-insoluble liquids or solids (e.g. hydrocarbons, higher alcohols, oils, fats, waxes and resins) into emulsions, dispersions or solutions, (2) as detergents, dish-washing agents, cleansing agents in hard water and dry cleaning compositions (3) as corrosion inhibitors (especially for ferrous metals) in metal cleaning compositions, paints, acid pickling baths and acid cleaning compositions (4) in petroleum products such as fuel oils, hydraulic fluids, cutting oils, lubricating oils and greases, and (5) to break water-in-oil emulsions obtained in flooding or acidification processes for recovering oil from oil-bearing strata or in petroleum refining processes.  In the above formula R is an alkylene radical of 2-6 carbon atoms and x is 1-6. Specification 415.718 is referred to.ALSO:Products obtained by acylating one mol of a di- or poly-amine H(NHR)xNH2 with 0.2 x to x mols of tall oil or rosin acids and then reacting the product with more than sufficient alkylene oxide to condense with all the remaining replaceable hydrogen atoms are used as froth flotation agents; in the formula R is an alkylene radical of 2-6 carbon atoms and x is 1-6.ALSO:Products obtained by acylating one mol of a di- or poly-amine H(NHR)xNH2 with O,2x to x mols of tall oil or rosin acids and then reacting the product with more than sufficient alkylene oxide to condense with all the remaining replaceable hydrogen atoms are used as additives to asphalt and road-building compositions, as airentraining agents for concrete, as bonding agents for various insulating and building materials and for incorporation into adhesives.  In the formula R is an alkylene radical of 2-6 carbon atoms and x is 1-6.ALSO:Products obtained by acylating one mol of a di- or poly-amine H (NHRxNH2 with 0.2 x to x mols of tall oil or rosin acids and then reacting the product with more than sufficient alkylene oxide to condense with all the remaining replaceable hydrogen atoms are used as wetting agents, disinfectants, insecticides, bacteriocides, fungicides and biocides. They can serve as emulsifying agents in mineral oil sprays, e.g. with D.D.T., 2 : 4-D, toxaphene, chlordane, nicotine sulphate, dieldrin, aldrin, lindane, B.H.C., heptachlor, I.P.C., chloro I.P.C. or methoxychlor.  In the formula R is an alkylene radical of 2-6 carbon atoms and x is 1-6.
