Introduced: September 1968
Description
C01D covers the synthesis, preparation, and chemical composition of inorganic compounds containing the alkali metals (lithium, sodium, potassium, rubidium, caesium, and francium). This includes hydroxides, halides, carbonates, sulfates, nitrates, and other salts of these metals, as well as their oxides and peroxides. The classification encompasses both industrial-scale production methods and laboratory synthesis routes for these compounds. Adjacent classes cover related materials such as compounds of alkaline earth metals (C01E) and general inorganic chemistry outside specific metal families (C01B).

Glossary
Binary compound Binary compounds A compound containing and limited to two distinct chemical elements. Inorganic compound inorganic compounds A compound devoid of a carbon atom and containing a non-metallic element or a compound containing a carbon atom, and satisfying one of the following criteria: the compound cannot have a carbon atom having direct bonding to another carbon atom; or the compound cannot have direct bonding between a carbon atom and a halogen or hydrogen atom; or the compound cannot have direct bonding between a carbon atom and a nitrogen atom by a single or double bond. The following are exceptions to the above and are to be considered as inorganic compounds: compounds consisting of only carbon atoms, (e.g. fullerenes), cyanogen, cyanogen halides, cyanamide, phosgene, thiophosgene, hydrocyanic acid, isocyanic acid, isothiocyanic acid, fulminic acid, unsubstituted carbamic acid, and salts of the previously mentioned acids and which contain the same limitations as to a carbon atom. Metal metals Any element other than a non-metal Moiety A specific part of a molecule. Non-metal non-metals The elements of hydrogen, carbon, halogen (fluorine, chlorine, bromine, iodine and astatine), oxygen, sulfur, phosphorus, silicon, nitrogen, boron, selenium, tellurium and noble gases (helium, neon, argon, krypton, xenon and radon) Preparation Preparations Covers synthesis, purification, separation, stabilisation or use of additives, unless a separate place is provided in the classification scheme.
