    A phosphine releasing composition suitable for use as a pest control agent comprising a mixture of aluminium phosphide, zinc or a zinc compound and a source of ammonia or ammonium ion, can be produced by mixing the components. The zinc or zinc compound in combination with the ammonia or ammonium ion protects the compositions when exposed to water vapor or liquid water against auto-ignition.

    This invention relates to a process for the production of hydrogen phosphorous from mixtures intended for combating agricultural pests.
    The aim of the invention is to enable the safe conduct of the process.
    Example 1, K70 MAh.h. of technical aluminum phosphide was added 25 mph., ammonium salt of carbamate acid and May 3, h, stearin. The mixture was stirred and divided into two parts, 2 m.h. was added to one part. zinc stearate and after which both mixtures are tableted. At 0 tablets each mixture is moistened with 30 ml of o.
    dusts at 20 ° C. Hydrogen phosphide is precipitated5 but the mixture containing zinc stearate is heated to 37 ° C, while 1 ° is without it.
    to 93 ° C. Increasing the temperature during hydrolysis to 100 ° G and higher results in self-ignition.
    Example 2 Into tablets of 3 g each are compressed the mixture, the composition of which is given. in table.1.
    10 tablets are hydrolyzed in a 400 ml beaker using 30 mg of water.
    The maximum reaction temperature for mixtures is g 41 ° C, C tablets of a mixture h reaches a temperature of 102 ° C with ignition and formation
    P OBAdded an additional series of tests in which ZnO is replaced with the same amount of ZnSO.,
    The reaction temperature of tablets with a ZnSO content reaches a maximum value of 39 ° C, tablets without ZnSOjj ignite to form PH,
    The same result is observed in a series of tests, when zinc borate is used as an additive instead of ZnSO. The composition without zinc reacts completely and the temperature rises to 98 ° C,
    ,,
    A method of producing phosphorous hydrogen, which includes hydrolysis of a mixture containing powdered aluminum phosphide and an ammonium compound, characterized in that, in order to ensure safe process management, zinc metal or its compound selected from the group containing Example 3, tablets are additionally introduced into the mixture 4 g each, pressed mixtures, the composition of which is a zinc mass. Inca stearap, is given in Table 2. ° main carbonate, sulfate
    or zinc borate, as a compound of 15 tablets of each composition of ammonium substitute, its chloride is used or hydrolyzed in a laboratory stabilized carbonate, or bicarbonate with the next 400 ml using a 30 ml 55 ratio of components, wt.%: water. The temperature of the reactions of the compounds Aluminum phosphide 46-70 A - o reaches a maximum of 45 Cj. Zinc metal mixture p ignites with the formation of - or its compound is O ,, 1-5,0 em PH, ammonium compound 10-50
    In a similar series of tests, carbonate and ammonium chloride, respectively, are used instead of the 1mmonium carbamate. In this case, the combinations of zinc-containing substances and the source of NH show a significantly weakened effect of hydrolysis.
    Parallel checks, when the same amount of NaCl is contained instead of ammonium carbamate, are shown to be ignited in hydrolysis tests in 80% of cases.
    Table 3 shows the kinetics of temperature changes during the hydrolysis of various mixtures.
    Example 4, Mix the components, May, h ,: aluminum phosphide 70; 20 ammonium carbamate 29.5; Zinc oxide 0.5; To 45 g of the mixture, 30 ml of water are added at 20 ° C. A slight warming up of the mixture (hand is sustained) occurs without ignition. Without the addition of a zinc compound, ignition occurs after 10–15 min.
    Example 5 „70 May, h, aluminum phosphide mixed from 19.5 to 30 May, h, aluminum stearate, 0 May, h, ammonium carbamate and 0.5 May, h, zinc oxide, 10 g of the mixture is subjected to hydrolysis using 10 ml water at 20 ° C. After 25 minutes, the temperature of the reaction
    35 tion reaches 33.6 ° C. Without the addition of zinc oxide, the mixture is already through
