The reaction is carried out to keep the conversion rate of the cyclopentadiene and/or the dicyclopentadiene at 50% or below when synthesising tricyclopentadiene from cyclopentadiene and/or dicyclopentadiene.
In this instance, there are 1,500 ppm or fewer of conjugated dienes, an impurity that can be found in cyclopentadiene and/or dicyclopentadiene.
The method for making tricyclopentadiene from cyclopentadiene and/or dicyclopentadiene is the subject of the current invention.
As a raw material for polymers, tricyclopentadiene itself can be polymerized into an amorphous polyolefin or hydrated to produce an alcohol and an ester of acrylic or methacrylic acid.
Furthermore, tricyclopentadiene hydroformylation and then hydrogenated to yield penta cyclopentadecane dimethanol, which can be used as a raw material for polyester, polyester carbonate, acrylic acid, and methacrylic acid resins.
In particular, a polycarbonate resin created by synthesising it with penta cyclopentadecane dimethanol offers exceptional qualities for use in optical materials such optical discs, optical fibres, eyeglass lenses, and industrial lenses.
The Global Tricyclopentadiene market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The purpose of this work is to clarify the effects of MgO promoters on the tricyclopentadiene (TCPD) hydrogenation reaction activity and the catalytic physico-chemical properties of Ru/-Al2O3 catalysts.
Coprecipitation was used to create Ru/Al2O3 and Ru-MgO/Al2O3 catalysts, which were synthesised as beads. The regenerated Ru-MgO/Al2O3 catalyst has a significantly higher specific surface area than the regenerated Ru/Al2O3 catalyst.
It has been proven that adding MgO has the ability to reduce the loss of a specific surface area throughout the repeated regeneration process.
The reducibility of the Ru/-Al2O3 catalyst was not significantly affected by the addition of MgO. The addition of MgO to the Ru/-Al2O3 catalyst has the effect of reducing the mobility of Ru atoms during recurrent regeneration at 650 °C, according to the results of XRD, CO chemisorption, and TEM imaging.
The presence of MgO presumably inhibited the sintering of Ru at the regeneration temperature of 650 °C, since it was proven that the degree of catalyst deactivation throughout four recurrent regeneration experiments was significantly lower than that with an unpromoted catalyst.
A potential contender for the role of reusable catalyst in the TCPD hydrogenation reaction is the Ru-MgO/-Al2O3 catalyst.
