标题:Process for the preparation of 1-amine-2-naphthol-4-sulfonic acid
发明人：ALBRECHT BERNHARD; BEYRICH JUERGEN
权利人:CIBA GEIGY CORP
摘要:There is disclosed an improved semi-continuous and continuous process for the preparation of 1-amino-2-naphthol-4-sulfonic acid by nitrosation of 2-naphthol, addition of bisulfite, acidification with mineral acid and reduction of the reaction product so obtained, which comprises charging the reactor with the nitrosating agent and simultaneously adding 2-naphthol and mineral acid simultaneously in separate streams in the semi-continuous process, or charging the reactor with the reaction mass and simultaneously adding 2-naphthol, mineral acid and the nitrosating agent in separate streams in the continuous process. The product can be further used, without isolation, for the synthesis of dyes.

标题 :Photochromic pigment
发明人：HU ANDREW TEH; WANG WEN HISHIN
权利人:NAT SCIENCE COUNCIL
摘要:The present invention is related to the synthesis of a novel photochromic compound. This compound is a reactive photochromic spirooxazine pigment. Its structure is shown as below: ##STR1## wherein R 1 is either a hydrogen atom or an alkyl group containing 1 to 5 carbon atoms. R 2 and R 3 are any of the following group: an alkyl group having 1 to 10 carbon atoms, or an alkyoxy group having 1 to 10 carbon atoms, or halogen atoms, or hydrogen atoms. The range of n is from 1 to 4, which represents the number of repeated units. This synthesized compound possesses a high thermal resistant property up to 241° C., and it may be added into low melting polyethylene terephthalate(PET) resins for direct melt spinning to prepare photochromic fiber. In addition, the reactive double bond of this compound can be copolymerized with other vinyl monomers, to prepare high molecular weight photochromic materials used for photochromic eye glasses and/or photochromic coating.
