Dyneema Â® SK60 is the only super-fiber with a density below 1.0 (the fiber can float on water). The specific gravity of Dyneema Â® SK60 is 0.97, which is the lowest value among super fibers and is lighter than water.
Benzalkonium chloride is a quaternary ammonium compound and is used as a preservative in many ophthalmic solutions. Typically in dilutions of 0.01% or less.lkyl triethanol ammonium chloride, benzethonium chloride, CETRIMIDE (cetyltrimethylammonium bromide), DYMED and POLYQUAD are also examples of quaternary ammonium compounds that are used in ophthalmic preparations.
Ammonia can also be used to make compounds in reactions which are not specifically named. Examples of such compounds include: ammonium perchlorate, ammonium nitrate, formamide, dinitrogen tetroxide, alprazolam, ethanolamine, ethyl carbamate, hexamethylenetetramine, and ammonium bicarbonate.mmonia is miscible with water. In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic. The maximum concentration of ammonia in water (a saturated solution) has a density of 0.880 g/cm 3 and is often known as '.880 ammonia'.
