Definitions

  • the invention provides a method of retaining an ammonia/ammonium chloride buffer system comprising the step of holding, storing and/or maintaining the ammonia/ammonium chloride buffer system in a vessel comprising the desiccant entrained polymer material.
  • FIG. 2 is a cross section taken along line 2-2 of FIG. 1 ;
  • FIG. 3 is a cross section similar to that of FIG. 2, showing a plug formed of another embodiment of an entrained polymer according to an optional aspect of the present invention.
  • FIG. 4 is a schematic illustration of an entrained polymer according to an optional aspect of the present invention, in which the active agent is a desiccant material.
  • FIG. 5 is a cross sectional view of a sheet formed of an entrained polymer according to an optional aspect of the present invention, adhered to a barrier sheet substrate;
  • the term “base polymer material” is defined as a material that includes a base polymer and optionally an additive. When no additive is added, the base polymer material is made of the base polymer. Optionally, the base polymer and the additive are miscible.
  • the term “channeling agent” or “channeling agents” is defined as a material that is immiscible with the base polymer and has an affinity to transport a gas phase substance at a faster rate than the base polymer.
  • a channeling agent is capable of forming channels through the base polymer when formed by mixing the channeling agent with the base polymer.
  • such channels are capable of transmitting a selected material through the entrained polymer at a faster rate than the selected material would be transmitted in the base polymer alone.
  • Suitable channeling agents may include a polyglycol such as polyethylene glycol (PEG), ethylene-vinyl alcohol (EVOH), polyvinyl alcohol (PVOH), glycerin polyamine, polyurethane and polycarboxylic acid including polyacrylic acid or polymethacrylic acid.
  • the channeling agent 35 can be, for example, a water insoluble polymer, such as a propylene oxide polymerisate-monobutyl ether, such as Polyglykol B01/240 produced by Clariant Specialty Chemicals Corp.
  • FIG. 5 illustrates an active sheet 75 formed of the entrained polymer 10 (shown in FIG. 5) used in the form of an insert 20 used in combination with a barrier sheet 80 to form a composite, according to an aspect of the invention.
  • the characteristics of the active sheet 75 are similar to those described with respect to the plug 55.
  • the barrier sheet 80 may be a substrate such as foil and/or a polymer with low moisture or oxygen permeability.
  • the substrate 80 is compatible with the active sheet 75 and is thus configured to thermally bond to the active sheet 75, when the active sheet solidifies after dispensing, as discussed below.
  • the desiccant loading level ranges from 20% to 80%, optionally from 40% to 70%, optionally from 40% to 60%, optionally from 40% to 50%, optionally from 45% to 65%, optionally from 45% to 60%, optionally from 45% to 55%, optionally from 50% to 70%, optionally from 50% to 60%, optionally from 55% to 65%, optionally from 55% to 60% by weight with respect to the total weight of the entrained polymer.
  • the desiccant entrained polymer absorbs NFF at 0.001- 0.1 % by weight in the environment in the headspace of a vessel holding a solution of 10% NFF in moisture (such as water).
  • the desiccant is a molecular sieve
  • the molecular sieve (3 A or 4A) adsorbs 0.001-0.1% ammonia by weight, optionally 0.002-0.01% by weight of the composition.
  • Example 1 Ammonia Adsorption by Desiccant
  • the ammonia adsorption by a molecular sieve was measured in an environment of 10% N3 ⁇ 4 in helium and the subsequent thermal desorption (TCD signals) measured. The results are summarized in Table 1. The test was conducted in helium to determine whether in fact the molecular sieve is absorbing ammonia, as opposed to absorbing only moisture particles found in ambient air, if the test were conducted under normal atmospheric conditions.

Abstract

L'invention concerne des compositions polymères entraînées configurées pour absorber l'ammoniac. L'invention concerne également un procédé de retenue d'une solution tampon d'ammoniac/chlorure d'ammonium. Le procédé comprend l'étape consistant à placer la solution tampon d'ammoniac/chlorure d'ammonium dans un récipient, qui contient un matériau polymère entraîné par un déshydratant qui n'est pas en contact direct avec la solution tampon d'ammoniac/chlorure d'ammonium. Le matériau polymère entraîné par déshydratant est constitué d'un polymère de base, d'un déshydratant et d'un agent de canalisation. Le procédé de l'invention maintient les propriétés de la solution tampon par régulation de la quantité d'ammoniac et/ou d'absorption d'humidité par le polymère entraîné par déshydratant.
