    Abstract: A process of producing methylhydroxyalkyl cellulose (MHAC) is described and involves in a first step (a), (i) introducing cellulose and a suspension medium into an autoclave, the suspension medium comprising 20 wt. % to 50 wt. % of chloromethane, based on the total weight of the said suspension medium, and (ii) spraying the cellulose in the autoclave with an aqueous alkali metal hydroxide solution, thereby alkalizing the cellulose and reacting the cellulose with chloromethane. In a second step (b), hydroxyalkylating agent is optionally introduced into the autoclave at a temperature above 60° C. In a third step (c) alkali metal hydroxide is introduced into the autoclave in a hyperstoichiometric quantity of at least +0.1 mol eq., relative to the chloromethane utilised. In a fourth step (d), at least one hydroxyalkylating agent is optionally introduced into the autoclave at a temperature above 60° C., and the introduced hydroxyalkylating agent is allowed to react for at least 20 min. In a fifth step (e), additional chloromethane is introduced into the autoclave in a hyperstoichiometric quantity of at least +0.2 mol eq., relative to the total alkali metal hydroxide utilised up to this point. In a sixth step (f), additional alkali metal hydroxide is optionally introduced into the autoclave, and the reaction is allowed to continue at a temperature of from 60° C. to 110° C. Finally, the suspension medium is removed by means of distillation, thus forming a distillate comprising residual chloromethane, and the methylhydroxyalkyl cellulose is isolated. Optionally, the isolated methylhydroxyalkyl cellulose may be washed, and dried. The addition of hydroxyalkylating agent occurs in step (b) and/or step (d).

    Abstract: A process for producing aminoalkyl-containing guar derivative is disclosed. The process entails a) dispersing a member selected from the group consisting of guar and guar derivative in a mixture of a water-miscible aprotic solvent and water and b) alkalyizing the member with a base to obtain a mixture containing an alkalized member and c) etherifying the mixture with an amino-containing reagent to obtained an etherified mixture and d) optionally neutralizing the etherified mixture to obtain a material system containing a reaction product and e) optionally filtering the material system to obtain the reaction product and f) optionally washing the reaction product and g) optionally drying the reaction product referred to in f) and h) optionally grinding the reaction product. The product thus obtained is suitable for producing hair conditioners and flocculation aids.
