The invention provides a novel hydrocarbon-containing carboxylic acid, hydrocarbon-containing sulfonic acid, hydrocarbon-containing sulfuric acid ester, or a salt thereof, and a surfactant. Each of them is a compound represented by the following formula (1):
CR1R2R4—CR3R5—X-A
wherein R1 to R5 are each H or a monovalent substituent; at least one of R1 or R3 is a group represented by the formula: —Y—R6; at least one of R2 or R5 is a group represented by the formula: —X-A or a group represented by the formula: —Y—R6; and As at the respective appearances are the same as or different from each other, and are each —COOM, —SO3M, or —OSO3M.
本发明提供了一种新型含碳氢化合物的羧酸、含碳氢化合物的磺酸、含碳氢化合物的硫酸酯或其盐,以及一种表面活性剂。它们中的每一种都是下式(1)所代表的化合物:
Cr1R2R4-CR3R5-X-A
其中 R1 至 R5 各为 H 或一价取代基;R1 或 R3 中至少有一个是由式表示的基团:-R2或R5中至少有一个是由式表示的基团:-X-A或由式: -Y-R6 所代表的基团;以及R2或R5中至少有一个是由式:-X-A代表的基团或由式:-Y-R6代表的基团;和As在各自的外表上彼此相同或不同,并且各自是-COOM、-SO3M或-OSO3M。
