    Abstract: 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.

    Abstract translation: 一系列单环，双和三环化合物，其中大多数在环中具有烯属不饱和键，其可以具有或不具有取代基。 虽然双环和三环可以是未取代的，但是具有烯属不饱和键，特别是多个烯属不饱和键的这些化合物在已知的聚合体系中是可聚合的和可共聚的。 它们是特别好的交联剂。 这些化合物在它们可以被氧化裂解的意义上可进一步用于在增塑剂和洗涤剂领域已知有用的相应的羧酸，醛和/或醇。 不具有烯属不饱和键的化合物也可被氧化裂解以产生氧化的，例如酸，醇或醛，已知有用的化合物。

    Abstract: A process for obtaining caffein from green coffee by withdrawing the caffein by means of recirculating moist carbon dioxide in supercritical state, which comprises removing the caffein from the caffein-loaded carbon dioxide by repeated treatment with water and recovering the caffein and the water from the resultant dilute aqueous caffein solution by recycling a stream of air or nitrogen under a superatmospheric pressure at about 1 to 5 atmospheres through the heated caffein solution and a heat exchanger, separating the caffein and the condensed water and recycling after admixture of cold caffein solution the gas through the heat exchanger in countercurrent flow relation and meeting the heat requirement by supplying heat to the hot caffein solution.

    Abstract translation: 一种通过在超临界状态下再循环湿二氧化碳来抽出咖啡因，从咖啡中获得咖啡因的方法，该方法包括通过用水反复处理从含有咖啡因的二氧化碳中除去咖啡因，并从所得物中回收咖啡因和水 通过加热的咖啡因溶液和热交换器在约1至5个大气压下在超大气压下再循环空气或氮气来稀释咖啡因水溶液，分离咖啡因和冷凝水，并在冷的咖啡因溶液加入气体后通过再循环 热交换器逆流流动关系，并通过向热咖啡因溶液供热来满足热需求。
