    • A process for the production of 1-aminoalkane-1,1-diphosphonates of the formula ##SPC1##Wherein R.sub.1 is a member selected from the group consisting of hydrogen, lower alkyl and phenyl, R.sub.2 and R.sub. 3 are members selected from the group consisting of hydrogen, alkyl having 1 to 22 carbon atoms, cycloalkyl having 5 to 6 carbon atoms, phenyl, alkylphenyl having 7 to 18 carbon atoms, phenylalkyl having 7 to 18 carbon atoms and together with the nitrogen atom, piperidino, pyrrolidino and morpholino, and X is a member selected from the group consisting of hydrogen, alkali metal, ammonium, pyridinium, guanidinium and mono-, di-, and tri-lower-alkanol-ammonium with the proviso that at least one of R.sub.1, R.sub.2 and R.sub.3 is other than hydrogen, which consists essentially in reacting a phosphorus trihalide selected from the group consisting of phosphosus trichloride and phosphorus tribromide with a monocarboxylic acid amide of the formula ##SPC2##wherein the molecular weight of said carboxylic acid amide is over 46 and R.sub.1, R.sub.2 and R.sub. 3 have the above assigned meanings, at a temperature of from 0.degree. to 75.degree.C, subjecting the resultant reaction product to hydrolysis, and recovering said 1-aminoalkane-1,1-diphosphonates. The 1-aminoalkane-1,1-diphosphonates, some of which are novel, are capable of forming complexes with heavy metals.

    • A biodegradable plastic material based on cellulose esters and possibly biodegradable carboxylic acid esters, glycol esters or glycol ethers as softener, composed of from about 50 to about 90 weight percent cellulose ester, from about 5 to about 40 weight percent softener, from about 5 to about 30 weight percent polyester and from about 0.5 to about 5 weight percent AQ-nylon. The biodegradable plastic material may also contain organic acids and/or acid esters and/or ethers different from the softener, and other additives, such as flame inhibitors, and is distinguished by excellent biodegradability, injection molding and blow molding characteristics. Also disclosed are articles made of the material of the invention and methods of making such articles. It is preferably molded into thin sheets and transparent plastic articles, preferably into enclosures/containers for oil lamps, eternal flame oil candles, composition lights, other cemetery light designs, votive lights and thin sheets.
