List Of Stoffs
During World War II, Germany fielded many aircraft and rockets whose fuels, and oxidizers, were designated (letter)-''Stoff'' (). The following list of stoffs refers to the World War II aerospace meanings if not noted otherwise. Meaning of ''stoff'' The German word ''Stoff'' (plural ''Stoffe''), like the English word ''stuff'', derives from Old French ''estoffe'', however the meanings are somewhat different. Stoff has a fairly broad range of meanings, including "chemical substance" or "matter", "fuel" and "cloth", depending on the context. The German names of the common elements hydrogen, oxygen and nitrogen are ''Wasserstoff'', ''Sauerstoff'' and ''Stickstoff'' ("hydrogen" being a scientific Greek neologism for "constituent of water", "oxygen" for "constituent of acids", "nitrogen" for "constituent of nitre", i.e. Potassium nitrate">saltpeter - although the German root ''stick-'' is derived from ''ersticken'', "to smother, suffocate", referring to its property of not supportin ...

Xylidine
Xylidine can refer to any of the six isomers of xylene amine, or any mixture of them. The chemical formula of xylidines is C8H11N or, more descriptively, (CH3)2C6H3NH2. The CAS number for the isomer mixture is 1300-73-8. They are colorless solids or liquids, although commercial samples can appear yellow or darker. They are miscible with ethanol and diethyl ether and slightly soluble in water. Xylidines are used in production of pigments and dyestuffs, and various antioxidants, agrochemicals, pharmaceuticals, hypergolic propellants, and many other organic chemicals. In World War II, xylidine was an important antiknock agent in very high performance aviation gasolines. Its purpose was to permit high levels of boost pressure in multiple-stage turbochargers, and thus high power at high altitudes, without causing detonation that would destroy the engine. The high pressures brought high temperatures of inlet air, making engines prone to knock. This use and storage stabilization methods w ...

Tonka (fuel)
Tonka is the name given to a family of German-designed rocket propellants first used under the name R-Stoff in the Wasserfall missile. Tonka propellants were later used in the Soviet Union, most commonly the TG-02 formulation, for example in the engine designs of the A.M. Isayev Chemical Engineering Design Bureau. Their use was later passed on along with other Soviet rocket technology to the Iraq, Iran, Afghanistan and later North Korea. Its name is a reference to the tonka bean. Being invented during the Second World War, it has no connection to the similarly named toys. The original R-Stoff formulation used by Nazi Germany was composed of 43% triethylamine and 57% xylidine. Its most common formulation, known as TONKA-250, TG-02 and under the code name Samin was made of 50% triethylamine and 50% xylidine, most commonly used with nitric acid or its anhydrous nitric oxide derivatives (classified as the AK-2x family in the Soviet Union) as the oxidiser; the combination is ...
