Abstract: Provided is a process for preparing bicyclo[2.2.2]octane-1,4-diol starting from cyclohexane-1,4-dione. The dione is reacted with certain trialkylsilyl halides or trimethylsilyl trifluormethanesulfonate in the presence of a non-nucleophilic base to afford a silyl-substituted diene, which is in turn reacted with ethylene and subsequently reduced to provide the title compound.
Abstract: The present invention relates to a process for making unsaturated polyester with high fumarate/maleate ratio. In particular, the process comprises making unsaturated polyester with ethylenically unsaturated compound as one of the starting material followed by isomerization using N,N-dimethylacetoacetamide (DMAA) as the catalyst. The polyester has a fumarate/maleate ratio of 90/10 or greater.

Abstract: Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.

Abstract: The invention provides a process for the preparation of a modified triethanolamine/fatty acid ester composition ratio by treatment of a conventional triethanolamine fatty acid ester composition with a hydrolytic enzyme. Also provided are novel mixtures of triethanolamine and mono-, di-, and tri-esters of fatty acids which are useful in the preparation of cationic surfactants useful in fabric softening applications. In one aspect, the method increases the triester fraction without significantly affecting the amount of mono-ester and unesterified species, which in turn adds to the flexibility in the formulation of the corresponding fabric softening compositions.

Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). The r-olefin may then be further separated into product streams in a separation zone downstream of the cracker furnace. In some cases, presence of recycle content hydrocarbons may facilitate more efficient operation of one or more distillation columns in the separation zone, including the demethanizer.

Abstract: Recycle content pyoil is cracked in a cracker furnace to make olefins and the coil outlet temperature of the r-pyoil fed coils can be lowered by adding r-pyoil to the cracker feedstock, or alternatively, the coil outlet temperature of the r-pyoil fed tubes can rise if the mass flow rates of the combined cracker stream containing r-pyoil are kept the same or lowered. Further, increasing the hydrocarbon mass flow rate by addition of r-pyoil can be achieved to also increase the output of ethylene and propylene in the cracker effluent. The cracker furnace can accept ethane and/or propane feedstocks in vapor form along with a liquid and/or vapor feed of r-pyoil.
