摘要:
The invention provides analogues of (S)-germacrene D analogue which have improved insect repellent properties compared to (S)-germacrene D analogue or which have insect attractant properties.
摘要:
A series of mono, bi and tricarbocyclic compounds, most of which have olefinic unsaturation in the ring, which may or may not have substituents thereon. While the bi and tricyclic rings may be unsubstituted, these compounds which have olefinic unsaturation, particularly multiple olefinic unsaturation, are polymerizable and copolymerizable in known polymerization systems. They are particularly good crosslinking agents. These compounds are further useful in the sense that they can be cleaved oxidatively, to corresponding carboxylic acids, aldehydes and/or alcohols which have known utility in the plasticizer and detergent arts. The compounds which do not have olefinic unsaturation can also be oxidatively cleaved to produce oxygenated, e.g., acid, alcohol or aldehyde, compounds having known utility.
摘要:
Systems and processes for maximizing the production of benzene and para-xylene from heavy reformate are provided. An integrated process and system may include a C9 dealkylation reactor, a transalkylation reactor, and a C10+ dealkylation reactor. The integrated process and system for producing benzene and para-xylene may be configured to additionally produce alkanes in the presence of hydrogen or olefins in the absence of hydrogen. The transalkylation reactor may perform transalkylation of product from the C9 dealkylation reactor and xylene isomerization.
