Application: Aqua ammonia (or ammonium hydroxide) is a solution of ammonia in water that has use as a common cleaning agent, in fertilizers, in food production as a levelling agent, acidity regulator, and antimicrobial agent. In most cases, this will not be necessary. �ꇆ��n���Q�t�}MA�0�al������S�x ��k�&�^���>�0|>_�'��,�G! PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. These couplets produce carbon dioxide bubbles upon contacting water (an alka seltzer tablet is an example of this type of compound). 13. 5. The dissolution time of the used ostomy pouch constructed of Estane X-4655 plastic material, with a wall thickness of 0.004 inches is then very rapid (about 3 minutes). 23, 1996, now U.S. Pat. Other products such as, diaper backing sheets made from the selectively dissolvable material, can also be made to dissolve with this technique. There are numerous large-scale ammonia production plants worldwide, producing a total of 144 million tonnes of nitrogen (equivalent to 175 million tonnes of ammonia) in 2016. Aqua ammonia can be prepared for laboratory use without the need to store the standard 34% by weight ammonium hydroxide solution which is fairly dangerous. The brine electrolysis process for production of ammonia does not lead to process-based CO2 emissions. In a few plants a portion of the CO2 produced is captured and used to produce urea or methanol. After use, the ostomy pouch or other device can be made to dissolve by placing the used pouch in ammonia water at a pH of 10.3 or higher.

In all of the cases, no mixing was employed, and pH readings were taken near the top of the container. If you have low storage capacity, our network of production sites and terminals ensure smaller batches get to you at exactly the right time. Second, the weight of the ammonia (NH3) present originally (either as anhydrous ammonia or in the original aqua ammonia) must equal the weight of the ammonia (NH3) in the final solution. A 10 g amount of the loaded sorbent sample was then poured into the pot. The ammonia gas would flow through one side of the packed bed, and the portion of the ammonia not adsorbed, if any, would exit the other side of the bed. �V��)g�B�0�i�W��8#�8wթ��8_�٥ʨQ����Q�j@�&�A)/��g�>'K�� �t�;\�� ӥ$պF�ZUn����(4T�%)뫔�0C&�����Z��i���8��bx��E���B�;�����P���ӓ̹�A�om?�W= Using the package containing a loaded molecular sieve provides the patient with a very easy and safe way of carrying the ammonia in a purse, pocket, etc., and to then change the pH of the toilet bowl water to 10.3 or higher simply by emptying the packet into the toilet bowl. By adsorbing the gas onto the molecular sieve or other sorbent material 7, the ammonia gas is sequestered and, therefore, is much safer to handle. 6 is a cross-sectional view of the packet used with the present invention. The molecular sieve or silica gel adsorbents, with adsorbed gas are referred to as loaded sorbents. While the pH value of the Ammonia water created by Silica Gel (14-20 Mesh) was one of the lowest values obtained, it was held over for further study due to the fact that it was believed to be much less expensive than the other materials. 5,729,956. If necessary, the release rate from the 13X (and other) sorbents can be slowed down by putting various additives into them, such as magnesium stearate. engine exhaust gases, smoke, fumes, flue gases, aerosols by adsorption, e.g. May be subject to detonation if allowed to dry out.
