Abstract
Systems and methods providing for the introduction of a dye, particularly a xanthene dye, and more particularly a rhodamine dye, to liquid anhydrous ammonia to discourage theft of the anhydrous ammonia and provide for leak detection in storage vessels. The dye will stain objects which come into contact with the liquid anhydrous ammonia allowing for the detection of such contact. Generally, the staining will be visible to the naked eye, but may also fluoresce when exposed to a particular light source such as ultra violet (UV) light.
Claims38
A method for staining a human being who comes into contact with liquid-state ammonia, the method comprising:
- introducing into liquid-state ammonia a xanthene dye to form a solution;
- having said human being come into contact with said solution;
- and
- allowing conversion of some of said liquid-state ammonia from a liquid to a gas while said human being is in contact with said solution, said dye creating a stain on said human being in contact with said liquid-state ammonia upon said conversion.
A method of staining materials used in the production of methamphetamine, the method comprising:
- providing a solution of a xanthene dye in ammonia;
- using said solution in the production of methamphetamine, thereby generating production byproducts that comprise said solution;
- staining materials contacted by at least one of said solution, said byproducts, or said methamphetamine;
- and
- detecting said staining on said materials;
- wherein said staining can be detected even in the absence of any one or more of said solution, said byproducts, and said methamphetamine.
A method for deterring the theft of liquid-state ammonia comprising:
- providing liquid-state ammonia in a vessel;
- adding a xanthene dye to said liquid-state ammonia;
- forming a solution of said ammonia and said dye, said solution generating a stain on objects that contact said solution;
- and
- indicating that said vessel includes said solution.
A method of generating stained methamphetamine, the method comprising:
- providing a solution of a xanthene dye in ammonia;
- using said solution in the production of said methamphetamine and
- having said xanthene dye exhibit color in said resultant methamphetamine.
