Abstract: PURPOSE: To obtain high density II-type anhydrous gypsum providing a water- added hardened body of high compressive strength by adding a predetermined amt. of a habit modifier to an above 20wt% flurry of gypsum sollowed by pressure hydrothermal treatment at a predetermined temp. without agittaing.  
     CONSTITUTION: 0.005W10wt% of a known habit modifier such as succinic acid is added to an above 20wt% slurry of gypsum and subjected to pressure hydrothermal treatment at above 170°C for above about 3 hr without agitating, thus obtaining II-type anhydrous gypsum with considerably enhanced properties such as a bulk density above 1, a water carrying capacity below 40% and a compressive strength of a hardened body above 100kg/cm 2 . Conditions outside the above ranges result in low bulk density of gypsum and low mechanical strength of a hardened body.

IPC: C07C35/08
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain an alcohol in a high yield and selectivity through suppressing byproduct formation by hydrating the corresponding olefin under specified conditions. SOLUTION: This alcohol is obtained by hydrating the corresponding olefin (an about 2-30C cyclic olefin) in the presence of a solid acid catalyst (e.g. zeolite) and a cyclohexylacetic acid compound bearing a substituent on the 2-sits (e.g. 2-cyclohexylacetic acid). For the hydration reaction, the amount of the 2- substituted cyclohexyl acetic acid compound to be used is 0.00001-20mol per mol of the olefin, the weight ratio of the catalyst to olefin is 0.001-200, and the molar ratio of the water or olefin is 0.1-100. The hydration reaction is carried out at 50-250 deg.C under a pressure of 0.1-2Mpa for 0.1-10h. Because esterification between the carboxylic acid as a reaction additive and the product alcohol is hard to occur, the objective alcohol can be isolated and purified from the reaction liquor in high recovery.

Abstract: PURPOSE:To make it possible to recover the drive power of a vehicle, by detecting a variation corresponding to the load of a suspension system component member to detect the float-up condition of one of wheels so that the function of differential gear operation is released. CONSTITUTION:A differential gear 4 driven by a power unit P through a propeller shaft 3 is disposed between wheels 2a, 2r, and is incorporated in a housing 7.
