Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound used as antiseptic/disinfectant. It causes the disruption of intermolecular interactions and the dissociation of lipid bilayers. The bacteriostatic (prevent growth) or bactericide (kill microorganism) activity of DDAC depends on its concentration and the growth phase of the microbial population. It is a broad spectrum biocidal against bacteria and fungi and can be used as disinfectant cleaner for linen, recommended for use in hospitals, hotels and industries. It is also used in gynaecology, surgery, ophthalmology, pediatrics, OT, and for the sterilization of surgical instruments, endoscopes and surface disinfection. In mice this disinfectant was found to cause infertility and birth defects when combined with Alkyl (60% C14, 25% C12, 15% C16) dimethyl benzyl ammonium chloride (ADBAC),. These studies contradict the older toxicology data set on quaternary ammonia compounds which was reviewed by the U.S. Environmental Protection Agency (U.S. EPA) and the EU Commission. In addition, DDAC, as well as other quaternary ammonia compounds, can lead to the acquisition of resistance by microorganisms when employed in sub-lethal concentrations. (Wikipedia).

Introduction to Inorganic and Organometallic Chemistry
So far we've learned a lot about general chemistry and organic chemistry, so let's move into inorganic chemistry and organometallic chemistry. In this series we will investigate all the elements on the periodic table that were ignored in organic chemistry, especially the transition metals.

Making cesium dichromate from chromium metal and cesium chloride
To explore an alternative route to make cesium metal, I made some cesium dichromate. Cesium dichromate can be reduced to cesium metal. Because I did not have any chromate compounds, I made the potassium dichromate myself by dissolving chromium metal and oxidizing it with hydrogen peroxid
