标题:一种紫外线吸收剂uv-329的制备方法
摘要:本发明提供了一种紫外线吸收剂uv‑329的制备方法,该方法包括由邻硝基氯苯经氨化,重氮化,偶合,一步还原,二步还原反应及后处理过程制备2‑(2'‑羟基‑5'‑特辛基苯基)苯并三唑产品.本发明采用浓度为10%~25%的氨水将邻硝基氯苯氨化后再与亚硝酸盐经重氮化反应生成重氮盐,该重氮化反应无需在强酸介质下进行,且综合利用了本公司已有产品的副产品氨水,三废低排放,且所需成本低;中间体偶氮产物的还原闭环过程采用2步还原法,避免了强还原剂直接将偶氮双键还原成胺,减少杂质生成,不但提高了产品纯度,同时提高了产品收率.

标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.
