Oligomeric (TH)FP, production and uses therefor

A method for the isolation of oligomeric 2, 2-difurylpropane (DTHFP) suitable for use on an industrial scale. A method can include using oligomeric 2, 2-difurylpropane, in particular, its use can be as a polar modifier for butadiene and styrene butadiene polymerisation so is to produce rubber. Utilising the material as an alternative to DTHFP in rubber production avoids subsequent leaching of the DTHFP into the environment as the oligomeric 2, 2-difurylpropane (DTHFP) gives rise to much lower levels of leaching.

A two-phase system for the clean and high yield synthesis of furylmethane derivatives over -SO3H functionalized ionic liquids

A new and effective unique two-phase reaction system is investigated for the high yield production of tri(furyl)methane from furfural and furan. This strategy includes the use of an acidic aqueous phase (water + -SO3H functionalized IL) and furan phase, which significantly suppresses polymer formation, thereby increasing the yield of tri(furyl)methane. Furan serves as a reactant as well as an extraction solvent for the recovery of the condensation products. For comparison, different -SO3H functionalized ionic liquids are prepared and their performances evaluated for the condensation of furan and furfural. The ionic liquids with alkyl chain linkers are found to be more effective and acidic than those with imidazolium linked N-sulfonic acids. In addition, an increase in carbon chain length between imidazole/tri-ethylamine/pyridine and -SO3H, increases the catalytic activity of the respective ionic liquids. Among the several prepared ionic liquids, the strongly acidic imidazolium based butylsulfonic acid 6 shows the best activity with a maximum condensation product yield of 84%. This strategy offers a significantly high yield of the condensation products of furan and furfural compared to the traditional mineral acid route. The activity and stability of the -SO3H functionalized 6 is confirmed from seven successful recycles, in which there is no reduction in its activity. Finally, this new strategy is successfully extended for the condensation of furan derivatives (e.g. furan and 2-methylfuran) with several different aldehydes, ketones and alcohols.

Hetero-Diels–Alder and Ring-Opening Reactions of Furans Applied to the Synthesis of Functionalized Heterocycles

Furans have been explored as a scaffold for the synthesis of a range of heterocyclic compounds, exploring their dienophilic behaviour towards nitroso- and azoalkenes as the first step. Acid-catalysed rearrangements of these cycloadducts, 4a,7a-dihydro-4H-furo[2,3-e][1,2]oxazines and 1,4,4a,7a-tetrahydrofuro[3,2-c]pyridazines, were studied. Using 1 equiv. of TFA, the bicyclic heterocycles derived from furan and 2-methylfuran were converted into furans bearing side-chains incorporating oxime and hydrazone groups by ring-opening of the six-membered ring with the concomitant aromatization of the furan ring. The use of TFA as solvent led to rearrangement via spirocyclic intermediates, followed by furan ring-opening to afford functionalized isoxazoles or pyrazoles. Furthermore, furo-oxazines derived from 2,5-dimethylfuran, in which furan aromatization is precluded, were converted efficiently into 6H-1,2-oxazines through a furan ring-opening reaction upon thermolysis in the presence of a catalytic amount of p-toluenesulfonic acid. The tetrahydrofuro[3,2-c]pyridazines derived from furan and dimethylfuran underwent acid-catalysed addition reactions, leading to 6-substituted hexahydrofuro[3,2-c]pyridazines, when in the presence of alcohols or water.

2,2-di(2-furyl) propane synthetic method

The invention provides a 2,2-di(2-furyl) propane synthetic method. The method comprises the step of making furan and acetone react in the presence of the catalyst metal triflates to generate 2,2-di(2-furyl) propane. By replacing an inorganic acid catalyst with the catalyst metal triflates, the requirement for environment-friendly and clean production of DFP is met. Continuous production is achieved through a pipeline reactor, and the automation degree is high. The usage of the organic solvent cyclohexane or ethyl alcohol is avoided during reaction, the operation environment is improved, and production cost is reduced. By optimizing the process route, the neutralizing procedure and the drying procedure are omitted, the production cycle is shortened, production cost is reduced, and the yield of the product DFP is increased.
