CODEN: JKXXAF. CLASS: ICM: A61K033-20. ICS: A61K006-00; A61K033-20; A61K047-02. APPLICATION: JP 90-286640 23 Oct 1990. PRIORITY: JP 90-81767 28 Mar 1990. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) A dental compn. contains as major components a hypochlorite metal salt, water, and alumina fine particles (BET sp. surface area 310 m2/g) with 350 cP viscosity. This compn. 1344-28-1 and 7778-66-7 are cas registry numbers of chemicals which are used as reagents here. is applied only to the target area of the tooth, and does not run into the surrounding tissue. Thus, a cleansing compn. was prepd. consisting of 100 parts by wt. 10 wt.% NaOCl soln. and 10 parts powdery Al2O3 with BET sp. surface area 100 m2/g. .

PRIORITY: JP 2002-209041 18 Jul 2002; JP 2002-237853 19 Aug 2002. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) This invention pertains to a method for producing chlorinated hydrocarbons with general formula of CnR1mHk(CR2R3Cl)j [wherein n = 1-12; m = 0-25; k = 0-25; j = 1-10; R1 = halo, O, N, S, or P; R2 and R3 = independently (un)substituted aliph. hydrocarbon, etc.], which comprises agitating a mixt. of a corresponding tertiary alc. and hydrochloric acid, and then contacting the resulting org. phase with a hydrogen chloride gas. For example, 1,4-bis(2-hydroxy-2-propyl)benzene was treated with aq. HCl in toluene to give 1,4-bis(2-chloro-2-propyl)benzene in 99.5% purity. This method allows the prodn. of chlorinated hydrocarbons in good yield with high purity. .
