摘要:
A method of preparing polydiorganosiloxane polyoxamide copolymers is described. These copolymers have at least one polydiorganosiloxane segment and at least two aminooxalylamino groups. The method can be used in the presence or absence of a solvent. Intermediates involved in the preparation of the copolymers are also described.
摘要:
A compound represented by the general formula below or a salt thereof is a useful intermediate in the production of a [2-(3,3,5,5-tetramethylcyclohexyl)phenyl]piperazine compound that has excellent cell adhesion inhibitory effect and cell invasion inhibitory effect and therefore is useful as a therapeutic or prophylactic agent for various inflammatory diseases and autoimmune diseases induced by the adhesion and invasion of leukocytes, such as inflammatory bowel diseases (particularly ulcerative colitis or Crohn's disease), irritable bowel syndrome, rheumatoid arthritis, psoriasis, multiple sclerosis, asthma and atopic dermatitis. wherein R1 and R2 independently represent hydrogen or a protecting group for an amino group, or R1 and R2 bond together to form an optionally substituted pyrrole ring.
摘要:
A method of producing a near-infrared absorbing dye compound, useful for image forming materials, infrared heat-sensitive recording devices, optical film materials, and the like, containing a process of reacting a compound represented by formula (I) with peroxomonosulfuric acid or its salt. wherein R111, R112, R121, R122, R131, R132, R141 and R142 each independently represent a hydrogen atom, an aliphatic group or an aromatic group; R103, R113, R123, R133 and R143 each independently represent a substituent; and n103, n113, n123, n133 and n143 each independently denote an integer from 0 to 4.
摘要:
This invention concerns a compound formed from a tertiary amine-carboxylic acid salt, where the carboxylic acid and tertiary amine are selected such that the catalyst salt is blocked at room temperature and becomes unblocked at an elevated temperature. The compound is useful as a heat activated urethane catalyst.
摘要:
A process for the manufacture of oxalic acid dihydrate in which an aqueous solution of sodium oxalate is contacted with hydrochloric acid and the resulting mixture then cooled to precipitate oxalic acid, followed by optional recovery and recycling of the sodium oxalate and hydrochloric acid into the reaction chamber.

摘要:
The present invention relates to a process for preparing oxalic acid and esters of oxalic acid. More particularly, this invention relates to a catalytic process for preparing oxalic acid and esters of same by the oxidative reaction, in a liquid phase, of carbon monoxide and water or alcohols with oxygen in the presence of redox systems.The catalyst systems used in accordance with this invention comprises a redox catalyst consisting essentially of a salt of Pd (II) and salts of a metal more electropositive than Pd having at least two oxidation states and, optionally, salts of alkaline metals, and co-catalytic amounts of at least one base having the formula R.sub.3 N in which the groups R which may be like or unlike and are selected from the group consisting of hydrogen and alkyl radicals having from 1 to 10 carbon atoms.
摘要:
The nitrous oxides released when ethylene oxide is introduced at 30*-70*C. into aqueous nitric acid of 50-70 percent by weight of HNO3 is recirculated thereto and gaseous oxygen is introduced into the nitric acid. A post-oxidation holding of the oxidation mixture for 8-24 hours at 30*-70*C. increases the yield of oxalic acid.
