This suggests that the diols form a diolate adduct that can undergo a competing SN2 reaction with water to cause isomerization of products. When using alcohols as reductants, there is an increase in yield of the stereospecific alkene. A mechanism for the DARe using alcohols and hydrogen was ...
it is useful for oxidative cleavage of alkenes, a reaction that converts alkenes (and alkynes) to carbonyl compounds. It also has many commercial uses, such as disinfecting surfaces, rooms, and drinking water. Ozone can be conveniently generated on demand by passing a stream of O2through high ...
与水反应(Reaction with water) 水也可以围绕烯烃中的双键加成,在工业上,使用该方反应来制备乙醇。该反应可在合适的温度和压力下,使用一种酸(例如磷酸-H3PO4等)作为催化剂,通过与水蒸气反应进行。详见9.3节。 硫酸的结构为: 问题小结Summary questions ...
This method uses a fixed bed reactor, in the presence of an acidic zeolite catalyst with a resin compound, the olefin hydration reaction with water, the resulting product was isolated as the alcohol. 该催化剂是将酸性分子筛粉体,聚合单体苯乙烯,聚合单体多烯基化合物以及制孔剂充分混合,在引发剂...
Isomerisation of n-alkenes (I) to isoalkenes (II) is effected at 250-550 deg.C using a fluorinated alumina catalyst, with the improvement that (i) the reaction is effected in the presence of 0.5-150 (pref. 2-130)wt.% water, based on the wt. of (I); (ii) fluorine lost from the...

Define alkene. alkene synonyms, alkene pronunciation, alkene translation, English dictionary definition of alkene. n. Any of a series of unsaturated, aliphatic hydrocarbons with a carbon-carbon double bond, having the general formula CnH2n. American Heri
The set of products that are released during the combustion reaction of materials. These products are the result of both complete and incomplete combustion but not of the pyrolysis process. Crude oil: Naturally occurring oil consisting primarily of hydrocarbons with some other elements such as sulfur...
