Aldol Condensation Wei-Hsuan Tsui 4/16/14 The reaction of an aldehyde with a ketone employing sodium hydroxide as the base is an example of a mixed aldol condensation reaction‚ the Claisen-Schmidt reaction. Dibenzalacetone is readily prepared by condensation of acetone with two equivalents of benzaldehyde -26 -95 113.9 1. Weigh 0.212 g of pure benzaldehyde directly into a 10 x 100 mm reaction tube. 2.

big ambition for diversification‚ but he never had to design and develop its own products and had never hired any design engineers. By mid-1993‚ Alex had hired a key-engineer from a Canadian firm and the company developed its own line of flexible couplings with an advanced design and efficient production process using the latest in production equipment. They developed a good marketing plan and made a successful new product. Cameron was then faced with how to market and sell the product. He needed to

benzoylation‚ acrylation‚ maleated coupling agents‚ isocyanates‚ permanganate and others are discussed. The chemical treatment of fiber aimed at improving the adhesion between the fiber surface and the polymer matrix may not only modify the fiber surface but also increase fiber strength. Water absorption of composites is reduced and their mechanical properties are improved.

CHAPTER TWO 2.0. LITERATURE REVIEW In a commercial transaction system‚ a system user uses a card device to interact with sales or transaction terminals to conduct cashless transactions. Each terminal processes data including a balance stored on the card device and updates the stored data at the end of the transaction. The system is specially designed for purchases of items or transactions of relatively small monetary value‚ where purchases are generated unattended by salespersons. In this manner

financially ready to make such a progress‚ the first option was‚ on one end‚ to wait and generate more profits leading to more financial stability through exports. On the other end‚ the company can choose to license the production of the flexible coupling with McTaggart. In this case‚ Cameron is the licensor and McTaggart‚ the licensee. The licensor shares patents‚ copyrights or trademarks and gets royalty fees in return. In 2004‚ Alex signed a five years licensing agreement with McTaggart. Following
