A naphthol derivative represented by the general formula (I), [wherein Y and Y′ indicate —(CONH)n—X or —COR; X is a phenyl group, a naphthyl group, an anthraquinonyl group, a benzimidazolonyl group or a carbazolyl group; R is a hydroxyl group, an alkoxy group having 1 to 6 carbon atoms, a halogen atom, a benzyloxy group, a phenyloxy group or a phenacyloxy group; R2 is a hydrogen atom, an alkaline metal, an alkyl group having 1 to 6 carbon atoms, an acyl group having 1 to 6 carbon atoms or a phenylalkyl group; Z is a group selected from the group consisting of a hydrogen atom, a halogen atom, a nitro group, a nitroso group and an amino group (Z may be substituted on any ring of the naphthalene ring); and n is an integer of 1 or 2; provided that R2 and Z do not simultaneously indicate a hydrogen atom when both R simultaneously indicate a hydroxyl group], and a process for producing the same. This naphthol derivative can be used as raw materials for synthesis, such as dyes, pigments, photosensitive materials and the like.
一种萘酚衍生物,由通式(I)表示,其中Y和Y'表示—(CONH)n—X或—COR;X是苯基、萘基、蒽醌基、苯并咪唑基或咔唑基;R是羟基、具有1至6个碳原子的烷氧基、卤素原子、苄氧基、苯氧基或苯乙酰氧基;R2是氢原子、碱金属、具有1至6个碳原子的烷基、具有1至6个碳原子的酰基或苯基烷基;Z是选自氢原子、卤素原子、硝基、亚硝基和氨基的基团(Z可以取代萘环的任何一个环上);n是1或2的整数;前提是当R同时表示羟基时,R2和Z不同时表示氢原子。本萘酚衍生物可用作合成染料、颜料、感光材料等原材料的原料。
