Appl. No.:

8/160773

International Classification:

A63G 2118

US Classification:

472117

Abstract:

A water slide includes a water distributor depressed within the slide surface near the upper end of the slide and one or more sets of water outlets to spread a small volume of water evenly accross the slide surface between two integral side walls. Water is drawn from a pool into which the lower end of the water slide projects and is pumped onto the slide surface through the water outlets using a conventional, inexpensive water pump, hoses and fittings. The dark color of the slide surface absorbs heat from the sun which is then transferred to the small volume of water flowing down the pitched slide surface. A support means and an access means are mounted to the water slide. The lower end of the slide has a steeper pitch, allowing the slide to be supported in various positions. The speed of descent can therefore be adjusted to accommodate various user needs.

Abstract:

A regioselective acetylation process is provided for converting a 2-methylnaphthalene compound to a 2-acetyl-6-methylnaphthalene compound. The process is conducted under liquid phase conditions using a new complexing agent which is regiospecific for the beta position of naphthalene and which is an electron-rich, carbon-based compound. A preferred such agent is hexamethylbenzene. Also provided is a novel method for producing a 2-acetyl-6-methylnaphthalene compound of relative high purity from isomer mixtures by recrystallization from a hydrocarbon solvent, such as n-octane, isooctane, or n-nonane.
