Usage

Description

Dicyclopentylether, also known as DCPE, is an organic chemical compound characterized by the presence of two cyclopentyl groups linked by an oxygen atom. It manifests as a colorless, flammable liquid with a distinctive sweet smell. DCPE is recognized for its stability and non-reactivity under standard conditions, although it can engage in vigorous reactions with potent oxidizers. Despite its generally low toxicity, it is imperative to exercise appropriate safety measures during its use and handling.

High selectivity of MCM-22 for cyclopentanol formation in liquid-phase cyclopentene hydration

Highly effective formation of cyclopentanol through the liquid-phase hydration of cyclopentene has been attempted on various zeolites catalysts. MCM-22 zeolite was the most selective catalyst, which actively converted cyclopentene to cyclopentanol with a selectivity up to 99%. The effects on the hydration of catalyst preparation method, reaction atmosphere and temperature have been investigated for the MCM-22 catalysts. On the basis of the effect of reaction atmosphere, the mechanism of liquid-phase cyclopentene hydration was proposed. The thermodynamic equilibrium between cyclopentene and cyclopentanol was suggested to control greatly the cyclopentene conversion. The cyclopentene conversion was increased to 10% by increasing the water/cyclopentene ratio. Poisoning using organic amines with different molecular sizes revealed that the hydration occurred mainly in the 10-membered ring channels of MWW structure, which had an elliptic aperture smaller than that of MFI structure, exhibiting a significant shape selectivity by suppressing the etherification cyclopentanol.

Synthesis of Benzyl Alkyl Ethers by Intermolecular Dehydration of Benzyl Alcohol with Aliphatic Alcohols under the Effect of Copper Containing Catalysts

Synthesis of benzyl alkyl ethers was performed in high yields by intermolecular dehydration of benzyl and primary, secondary, tertiary alcohols under the effect of copper containing catalysts. The formation of benzyl alkyl ethers occurs with participation of benzyl cation.

Process for the production of symmetrical ethers from secondary alcohols

Secondary alcohols are converted to symmetrical secondary alkyl ethers in high selectivity. The method employs acidic solid metallosilicate catalyst particles to accomplish the etherification by selective intermolecular dehydration of secondary alcohol to form di-secondary alkyl ethers. Preferably, the catalysts are solid shape selective aluminosilicate particles, especially zeolite such as ZSM-5, zeolite HY and zeolite Beta. Continuous separation of by-product olefin and ether during the etherification reaction improves selectivity.
