Ethyl iodide (also iodoethane) is a colorless flammable chemical compound. It has the chemical formula C 2 H 5 I and is prepared by heating ethanol with iodine and phosphorus . [ 2 ] On contact with air, especially on the effect of light, it decomposes and turns yellow or reddish from dissolved iodine.
1,2-Diiodoethane can be prepared by the reaction of ethylene with iodine (I 2): [2] C 2 H 4 + I 2 ⇌ C 2 H 4 I 2. 1,2-Diiodoethane is most commonly used in organic synthesis in the preparation of samarium(II) iodide or ytterbium(II) iodide in an inert solvent such as THF. [3] Sm + ICH 2 CH 2 I → SmI 2 + H 2 C=CH 2
In the presence of aluminium trichloride, 1,1-dichloroethane will converted to 1,1-diiodoethane. [3] The preparation of 1,1-diiodoethane from gem-dihaloalkanes [3] To be specific, mix 0.4 mol (~39.6 g) of 1,1-dichloroethane with 1.2 mol (~187 g) of ethyl iodide, and ~2.0 g of aluminium chloride. Heat for three hours using steam bath.
For example, sodium acetate dissociates in water into sodium and acetate ions. Sodium ions react very little with the hydroxide ions whereas the acetate ions combine with hydronium ions to produce acetic acid. In this case the net result is a relative excess of hydroxide ions, yielding a basic solution. Strong acids also undergo hydrolysis.
Water softeners are usually regenerated with brine containing 10% sodium chloride. [7] Aside from the soluble chloride salts of divalent cations removed from the softened water, softener regeneration wastewater contains the unused 50–70% of the sodium chloride regeneration flushing brine required to reverse ion-exchange resin equilibria.
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Ether synthesis by reaction of salicylaldehyde with chloroacetic acid and sodium hydroxide [1] The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol . This reaction was developed by Alexander Williamson in 1850. [2]
Drain cleaners usually contain a strong base such as sodium hydroxide that decomposes hair and converts fats into water-soluble products. The reaction is exothermic, releasing heat to soften the fats. Drain cleaners can also contain aluminum, which reacts with sodium hydroxide to produce bubbles of hydrogen gas that help to break up the clog. [11]
