    • A method for manufacturing a piezoresistive material, a piezoresistive composition and a pressure sensor device are provided. The piezoresistive composition includes a conductive carbon material, a solvent, a dispersive agent, an unsaturated polyester and a crosslinking agent. The conductive carbon material is selected from a group consisting of multi-wall nanotube, single-wall carbon nanotube, carbon nanocapsule, graphene, graphite nanoflake, carbon black, and a combination thereof. The solvent is selected from a group consisting of ethyl acetate, butyl acetate, hexane, propylene glycol mono-methyl ether acetate and a combination thereof. The dispersive agent includes block polymer solution with functional groups providing the affinity. The unsaturated polyester is selected from a group consisting of an ortho-phthalic type unsaturated polyester, an iso-phthalic type unsaturated polyester, and a combination thereof. The crosslinking agent is selected from a group consisting of ethyl methyl ketone peroxide, cyclohexanone diperoxide, dibenzoyl peroxide, tert-butyl peroxybenzoate and a combination thereof.

    • The present invention relates to an improved process for producing an organic carboxylic acid having (n+1) carbon atoms by reacting an alcohol having n carbon atoms with carbon monoxide in the presence of a rhodium catalyst system. More particularly, the present invention relates to carbonylation of alcohol such as methanol catalyzed by a rhodium system to produce acetic acid. The characteristic of the present invention is the addition of a catalyst stabilizer in the reaction medium to avoid or to alleviate the precipitation of the catalyst in the liquid phase. The catalyst stabilizer as used herein is a pyridine derivative having substituent(s) of such as (CH2)mCOOR or (CH2)mSO3R (R═H or hydrocarbons; m=0-6).
    • 本发明涉及通过在铑催化剂体系的存在下使具有n个碳原子的醇与一氧化碳反应制备具有(n + 1)个碳原子的有机羧酸的改进方法。 更具体地说,本发明涉及通过铑体系催化的醇如甲醇的羰基化以产生乙酸。 本发明的特征是在反应介质中加入催化剂稳定剂以避免或减轻催化剂在液相中的沉淀。 本文所用的催化剂稳定剂是具有(CH 2)m COOR或(CH 2)m SO 3 R(R = H或烃; m = 0-6)取代基的吡啶衍生物。
