Strontium carbonate a mineral, strontium carbonate is prepared synthetically in one of two manners. First of which is from naturally occurring celestine also known as strontium sulfate (SrSO) or by using soluble strontium salts by the reaction in solution with a soluble carbonate salt (usually sodium or ammonium carbonates). For example if sodium carbonate was used in solution with strontium nitrate: Sr(NO) + NaCO → SrCO + 2 NaNO . The most common use is as an inexpensive colorant in fireworks. Strontium and its salts emit a brilliant red color in flame. Unlike other strontium salts, the carbonate salt is generally preferred
Nitrate ester Nitrate ester A nitrate ester is the organic functional group with the formula RONO, where R stands for any organic residue. They are the esters of nitric acid and alcohols. A well-known example is nitroglycerin, which is not a "nitro" compound, despite its name. Nitrate esters are typically prepared by condensation of nitric acid and the alcohol: For example, the simplest nitrate ester, methyl nitrate, is formed by reaction of methanol and nitric acid in the presence of sulfuric acid: This condensation is sometimes called "nitroxylation". The thermal decomposition of nitrate esters mainly yields the gases molecular nitrogen (N) and
