The present invention provides a hydrolysate of a lignocellulosic material, and specifically a method of using a hydrolysis treatment liquid obtained by a hydrolysis treatment of a lignocellulosic material before kraft cooking in order to obtain dissolving pulp for uses other than use of a fuel. Specifically, the present invention provides a dispersant containing the hydrolysate obtained by hydrolysis treatment of the lignocellulosic material. The dispersant of the present invention has excellent dispersibility for a substance such as an inorganic substance and an organic substance without limitation of powder, particulate, granular, fiber, and flat plane shapes.

Dispersant

Disclosed is a biodegradable composition characterized by compounding yeast (A) and biodegradable plastic (B) at a particular proportion. The purpose is to provide a biodegradable composition having very good biodegradability and additional fertilizer effect, making good use of the characteristics of yeast.

Biodegradable composition and method of producing the same

Lead storage battery containing a negative electrode active substance

A lignin composition having a content of aluminum or iron or both at 0.05 to 5 wt. % (based on the solids of the lignin solution) and a content of extracts with chlorotrifluoroethylene dimer at 0.01 to 0.4 wt. % (based on solids in lignin solution). The lignin compositions possess high surface tension and are suitable as dispersing agents for cement.

Lignin composition, method of producing the same and dispersing agent

Novel condensates comprising bisphenols and aromatic aminosulfonic acids, in particular, novel 4-aminobenzenesulfonic acid-2,2-bis (hydroxyphenyl)propaneformaldehyde condensates, and methods for their production are disclosed. The novel condensates are useful as a dispersant for disperse dyes, an additive for carbonaceous fine powder-water slurries and as a water reducing agent for cement.

Production of novel condensates comprising bisphenols and aromatic

A production method of novel condensates comprising bisphenols and aromatic aminosulfonic acids, in particular, novel 4-aminobenzenesulfonic acid-2, 2-bis(4-hydrocyphenyl)propaneformaldehyde type condensate and said condensate itself are disclosed. Uses of condensates as a dispersant for disperse dye, additive for carbonaceous fine powder-water slurry and water-reducing agent for cement are also claimed.
