Cyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. The amine itself is an effective corrosion inhibitor. It has been used as a flushing aid in the printing ink industry. [5]
Curtius rearrangement. The Curtius rearrangement (or Curtius reaction or Curtius degradation ), first defined by Theodor Curtius in 1885, is the thermal decomposition of an acyl azide to an isocyanate with loss of nitrogen gas. [1] [2] The isocyanate then undergoes attack by a variety of nucleophiles such as water, alcohols and amines, to yield ...
An arylcyclohexylamine is composed of a cyclohexylamine unit with an aryl moiety attachment. The aryl group is positioned geminal to the amine. In the simplest cases, the aryl moiety is typically a phenyl ring, sometimes with additional substitution. The amine is usually not primary; secondary amines such as methylamine or ethylamine, or ...
The simplest case refers to the formation of a strictly linear polymer by the reaction (usually by condensation) of two monomers in equimolar quantities. An example is the synthesis of nylon-6,6 whose formula is [−NH−(CH 2) 6 −NH−CO−(CH 2) 4 −CO−] n from one mole of hexamethylenediamine, H 2 N(CH 2) 6 NH 2, and one mole of adipic acid, HOOC−(CH 2) 4 −COOH.
Eticyclidine (PCE, CI-400) is a dissociative anesthetic drug with hallucinogenic effects. It is similar in effects to phencyclidine but is slightly more potent. PCE was developed by Parke-Davis in the 1970s and evaluated for anesthetic potential under the code name CI-400, but research into PCE was not continued after the development of ketamine, a similar drug with more favourable properties.
The Antikythera mechanism (/ ˌ æ n t ɪ k ɪ ˈ θ ɪər ə / AN-tik-ih-THEER-ə, US also / ˌ æ n t aɪ k ɪ ˈ-/ AN-ty-kih-) [1] [2] is an Ancient Greek hand-powered orrery (model of the Solar System), described as the oldest known example of an analogue computer [3] [4] [5] used to predict astronomical positions and eclipses decades in advance.
Butler–Volmer equation. In electrochemistry, the Butler–Volmer equation (named after John Alfred Valentine Butler [1] and Max Volmer ), also known as Erdey-Grúz –Volmer equation, is one of the most fundamental relationships in electrochemical kinetics. It describes how the electrical current through an electrode depends on the voltage ...
The Feynman–Kac formula, named after Richard Feynman and Mark Kac, establishes a link between parabolic partial differential equations and stochastic processes.In 1947, when Kac and Feynman were both faculty members at Cornell University, Kac attended a presentation of Feynman's and remarked that the two of them were working on the same thing from different directions.
