  • High-strength cable
    Patent number: 8240119
    Abstract: A high-strength cable having a twisted layer of non-metallic reinforcing elements in outer coatings is disclosed. The reinforcing elements include coating elements, fiber elements of copolyparaphenylene-3,4?-oxydiphenyleneterephthalic amide disposed in the coating elements, and filling materials filled between the fiber elements, respectively. The lateral compression stress of the fiber elements of the copolyparaphenylene-3,4?-oxydiphenyleneterephthalic amide is 75 cN/dtex or more.

  • Non-pollutional process for producing aromatic nitro compounds without using a mineral acid
    Patent number: 5237077
    Abstract: The present invention relates to a process for producing an aromatic nitro compound by introducing a nitrogen oxide gas and ozone-containing oxygen or air into a halogenated organic solvent dissolving or suspending therein an aromatic compound, thereby subjecting the aromatic compound to nitration. By the use of a system comprising the nitrogen oxide and ozone-containing oxygen or air as the nitrating agent, the aromatic nitro compound can be produced under mild conditions without using any mineral acid. In addition, the various disadvantages due to the use of mineral acid in the conventional process can be avoided by the process of the present invention.
