Patent number: 7288677Abstract: This invention provides aromatic diimines which have imino hydrocarbylidene groups with at least two carbon atoms, and aromatic secondary diamines which have amino hydrocarbyl groups with at least two carbon atoms. Both the aromatic diimines and the aromatic secondary diamines either are in the form of one phenyl ring, or are in the form of two phenyl rings connected by an alkylene bridge; each position ortho to an imino group or an amino group bears a hydrocarbyl group. When in the form of one phenyl ring, there are two imino groups on the ring or two amino groups on the ring; the imino groups or amino groups are meta or para relative to each other. When in the form of two phenyl rings connected by an alkylene bridge, there is either one imino group or one amino group on each phenyl ring. Also provided are processes for forming diimines and secondary diamines.Type: GrantFiled: March 27, 2006Date of Patent: October 30, 2007Assignee: Albemarle CorporationInventors: John Y. Lee, Paul L. Wiggins, Judit Orgad, Mahmood Sabahi, Vernon O. Brandt

Patent number: 7271298Abstract: A process for isolation and purification of xanthophylls crystals from plant oleoresin is disclosed. The organic solvents involved in the process is no other than food grade alcohol. The process includes saponifying the plant oleoresin containing xanthophyll diesters, neutralizing the saponified reaction mixture with an acid and washing water-soluble impurities and other fat-soluble oil with warm water and alcohol, respectively. The process can improve purity and yield of products, by which the content and the recovery of xanthophylls are as high as 90% and 80% respectively. And the process is economical and easy to perform in industrial production.Type: GrantFiled: January 23, 2006Date of Patent: September 18, 2007Assignee: Zhe Jiang Medicine Co., Ltd. Xinchang Pharmaceutical FactoryInventors: Xinde Xu, Bin Shao, Di Zhou, Shuangming Ye, Yanfeng Wang, Boqiu Chen

Patent number: 7259226Abstract: The present invention is related to a series of polyesters based upon the reaction of dimer acid, dimer alcohol and Guerbet alcohol. The resulting polyester is a high molecular weight product that is well tolerated by the skin and has outstanding emolliency. The Guerbet alcohol, being mono hydroxyl is a capper portion of the polymer, the dimer alcohol is a chain extender having two hydroxyl groups and the dimer acid is a diacid that reacts with the hydroxyl groups on the Guerbet and dimer alcohol to make the polyester.Type: GrantFiled: March 7, 2005Date of Patent: August 21, 2007Assignee: Zenitech LLCInventor: Anthony J. O'Lenick, Jr.

Patent number: 7252839Abstract: A delivery system including a body construction (7) and at least one capsule (8) containing a pharmaceutical composition, the capsule having at least a first end and a second end. The body construction (7, 12, 34) has at least two locking parts (9, 10), each locking part (9, 10) having at least a first end and a second end, the first end of each locking part (9, 10) having a surface adapted to face and cover one of the at least first and second ends of the capsule (8). The diameter of at least one of the locking parts varies along its length between the first end and the second end, and the capsule (8) is mounted between the at least two locking parts. Also disclosed is a manufacturing process of a delivery system, the system including a body construction and at least one capsule containing a pharmaceutical composition.Type: GrantFiled: September 4, 2003Date of Patent: August 7, 2007Assignee: Schering OyInventors: Esa Hallinen, Heikki Lyytikäinen, Pentti Järvelä, Ilkka Kivi
