The present invention is concerned with a reactive surfactant composition for emulsion polymerization, which is able to micronize the particle diameter of a polymer emulsion and to reduce the addition amount of the reactive surfactant composition to be used. The reactive surfactant composition for emulsion polymerization of the present invention contains a reactive anionic surfactant (component A) represented by the following formula (I): wherein AO represents an alkyleneoxy group having a carbon number of 3 or more and 18 or less; EO represents an ethyleneoxy group; p represents an integer of 1 or more and 15 or less; m' represents an integer of 0 or more; n&#x2032; represents an integer of 0 or more; Mrepresents a hydrogen ion or a cation; and plural kinds of AOs may coexist.

According to the present invention, a bulky sheet can be obtained without reducing the effect of a sizing agent. Thus, an ester compound having the melting point of not more than 100&deg; C. selected from (A) an ester compound of a polyhydric alcohol and a fatty acid and (B) an ester compound of a polyhydric alcohol and a fatty acid further including from more than 0 mole to less than 12 moles on the average of C oxyalkylene groups per 1 mole of the said ester compound is used as a paper bulking promoter.

A process for producing an alcohol from a fatty acid ester, a fatty acid triglyceride or a fatty acid by continuously catalytically reducing the starting material in the presence of a hydrogenation catalyst is disclosed. In the process of the present invention, two reactors (i.e., the main reactor located upstream and the after reactor located downstream) being located in series are employed. In the process of the present invention, two reactors are employed and the temperatures thereof are individually controlled, whereby the conversion ratio is elevated while suppressing the formation of hydrocarbon and aldehyde by-products. Thus, an alcohol of extremely high quality and high purity can be produced. Further, the process of the present invention makes it possible to omit any post-treatment for eliminating the by-products. Furthermore, the active life of the hydrogenation catalyst can be remarkably prolonged by using three reactors (i.e., the guard reactor, the main reactor and the after reactor).
