Definitions

  • This invention relates to substituted phosphono-amides, to processes for their production, to compositions containing such compounds, and to the use of such compositions to impart flame-resistance to cellulose and cellulosecontaining materials.
  • a known single-bath process involving a metal oxide entails padding a dispersion of a chlorinated hydrocarbon and finely divided antimony oxide on to the fabric and heating to render the finish wash-proof.
  • the active agent in this case is antimony oxychloride which is formed by the interaction of the oxide with the hydrogen chloride liberated from the chlorinated hydrocarbon when flame temperatures are approached.
  • the handle of the finished fabric is deleteriously affected and this is especially so with fine, closely-woven fabrics.
  • Esterification of cellulosic materials with, for instance, diammonium hydrogen orthophosphate has also been used to impart flame resistance. It has the disadvantage that the treated-material is susceptible to ion-exchange in hard water or soap solutions, the inactive calcium or sodium salt being formed. The flame resistance must then be regenerated by steeping the material in ammonium chloride solution.
  • the present invention provides a new class of substituted phosphono-amides which can be used in conjunction with aminoplasts to confer flame-resistance on cellulosic materials by a process which avoids some or all of the disadvantages of known processes.
  • the new substituted phosphono-amides are those of the general Formula I:
  • R represents hydrogen, allyl or alkyl of up to six carbon atoms
  • n is either 1, when X represents hydrogen, methyl or a CH CON-HCH OR group, or zero, when X represents a -CH CONHCH OR group
  • R and R either each represent the same or different alkyl, alkenyl, cycloalkyl, cycloalkenyl, alkoxyalkyl, alkoxyalkenyl, aryl, alkoxyaryl, or alkylene residues, which may be substituted by one or more chlorine and/or bromine atoms, the terminal valency of any such alkylene residue being linked to a group of Formula II:
  • R and R together represent, a polymethylene chain containing from two to six carbon atoms which may be linked to a second polymethylene chain contain ing two to six carbon atoms, via a spiro carbon, which polymethylene chainsmay be substituted by one or more chlorine and/or bromine atoms and/or methyl groups, the terminal valencies of the second polymethylene chain, if such be present, being linked to a group of Formula II.
  • Preferred compounds of Formula I are those wherein R and R either represent identicalalkyl groups, particularly those; containing up to four carbon atoms, or identical alkenyl or alkylene groups, particularly those containing from two to four carbon atoms; or together represent a polymethylene group containing from two to sixcarbon atoms. Also preferred are those compounds wherein R and -R together represent a polymethylene chain containing from two to three carbon atoms linked to a second such polymethylene chain via a spiro-carbon. Further preferred are those compounds of Formula I wherein each of R and R contains up to four chlorine and/ or bromine atoms.
  • preferred compounds are N-hydroxymethyl-3-(diethylphosphono) propionamide, N-hydroxymethyl-3-(diallylphosphono) propionatnide,
  • the compound of Formula VII is added to an aqueous solution of formaldehyde, the pH of the reaction mixture being maintained at or above 7.0 by the addition of an alkaline-reacting substance, suitably sodium hydroxide, and to maintain the temperature of the reaction mixture between 40 C. and 60 C.
  • an alkaline-reacting substance suitably sodium hydroxide
  • the solution may be cooled and filtered.
  • the product may be incorporated in the flameproofing compositions hereinafter described as the aqueous solution so obtained.
  • Another preferred method comprises heating a compound of Formula VII with paraformaldehyde in the presence of an alkaline-reacting substance, suitably potassium carbonate or sodium carbonate. Temperatures between about 75 C. and about 150 C., may be employed; if a solvent, such as methanol is added, reaction may be effected at lower temperatures, e.g. about 50 C.
  • an alkaline-reacting substance suitably potassium carbonate or sodium carbonate.
  • R O o R 0 H VIII wherein R and R are as hereinbefore defined except that references to the group P.(CHz)n.(['/HCONIICI.I1OR o X should be understood as references to the group o with acrylamide, methacrylamide, itaconamide, fumaramide or maleamide.
  • a non-acidic condensation catalyst preferably an alkaline catalyst.
  • the latter may be an alkali metal, an alkaline P.CH:CH2C ONHCHzOH metal amide, an alkali metal hydride, a secondary or tertiary amine, an alkali metal salt of the phosphite diesters, a quaternary ammonium hydroxide or basic ionexchange resin, and, especially, a solution or slurry of an alkali metal alkoxide in the corresponding alcohol.
  • a volatile inert solvent particularly a high-boiling liquid, may be added to moderate the reaction. Addition of a solvent is desirable but not essential, when the unsaturated amide is a solid under the reaction conditions.
  • compounds of the general Formula I wherein R denotes an alkyl group containing from one to six carbon atoms are produced by reacting a compound of Formula I in which R is hydrogen with an aliphatic monohydric alcohol containing from one to six carbon atoms, in the presence of an acid.
  • compounds of the general Formula I wherein R denotes an allyl group are produced by reacting a compound of Formula I in which R is hydrogen with allyl alcohol in the presence of an acid.

  • suc-h compositions also contain a latent acid catalyst to accelerate curing of the aminoplast and cross-linking of the compound of the general Formula I having two CONHCH OR groups.
  • the latent acid catalysts which may be used are well-known in the process of curing aminoplasts on cellulosic materials, and include for example, ammonium chloride, ammonium dihydrogen orthophosphate, magnesium chloride, zinc nitrate, etc.
  • the aminoplast employed may be a condensation product of formaldehyde with urea or a derivative thereof such as ethyleneurea or, preferably, with melamine or a derivative, such as an ether of the said melamineforma-ldehyde condensation product.
  • a process for rendering cellulose-containing materials flame-resistant by treatment with such a composition followed by heating the treated material to cure the said aminoplast, and/or to effect cross-linking of the compound of general Formula I containing two CONHCH OR groups is within the scope of the invention.
