The Misuse Of Drugs Act was amended in 2002 to include a "catch most" clause outlawing every drug, and possible future drug, from the LSD and MDMA (phenethylamine) chemical families (including 2C-E). The amendment is a near verbatim quote from the books of the American biochemist Alexander Shulgin , who obtained a PhD from the University of ...
Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...
In chemistry, a reaction intermediate, or intermediate, is a molecular entity arising within the sequence of a stepwise chemical reaction. It is formed as the reaction product of an elementary step, from the reactants and/or preceding intermediates, but is consumed in a later step. It does not appear in the chemical equation for the overall ...
2CE-5iPrO (5-iPrO-2C-E) is a psychedelic substituted phenethylamine derivative related to 2C-E, but with the 5-methoxy group extended to isopropoxy. Similar to related "tweetio" compounds such as 2CD-5EtO , it has a longer duration of action than 2C-E but is otherwise similar in activity, although it shows reduced antiinflammatory actions.
Description: This publication laid out a logical system for naming chemical substances (mainly chemical elements and inorganic compounds). Importance: Prior to this publication, a multitude of names were often used for the same substance. This publication led to an international consensus on how to name chemical substances.
In the reaction depicted below, [4] the Gilman reagent is a methylating reagent reacting with an alkyne in a conjugate addition, and the ester group forms a cyclic enone. Scheme 1. Example Gilman reagent reaction
For example, with sulfite in acidic environments it reacts quickly and completely. When ceric compounds are reduced, so-called cerous compounds are formed. The reaction taking place is: Ce 4+ + e − → Ce 3+ The cerous ion is colorless. Ceric sulfate is used in analytical chemistry for redox titration, often together with a redox indicator.
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [1] When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated.
