A production method of a cationized cellulose or a cationized hydroxyalkylcellulose, including step 1 for adding a cationizing agent to cellulose and mechanically decrystallizing the cellulose and step 2 for adding a basic compound to the mixture obtained in step 1 and mechanically decrystallizing the cellulose, or a production method of a cationized cellulose or a cationized hydroxyalkylcellulose, including a step 3 for adding a basic compound to cellulose and mechanically decrystallizing the cellulose and step 4 for adding a cationizing agent to the mixture obtained in step 3 and mechanically decrystallizing the cellulose. The cellulose and the cationizing agent are allowed to react with each other in step 2 or step 4.

Method for producing cationized cellulose and method for producing cationized hydroxyalkyl cellulose

The present invention relates to a process for producing a decrystallized cellulose having a reduced cellulose I-type crystallinity from a cellulose-containing raw material in an efficient manner with an excellent productivity. In accordance with the present invention, there is provided a process for producing a decrystallized cellulose from a raw material comprising at least 20% by weight, based on the weight of the raw material excluding water contained therein, of a cellulose having a cellulose I-type crystallinity of more than 33% as calculated from the following formula:Cellulose-type Crystallinity (%)=[()/]&#xd7;100wherein Iis a diffraction intensity of a lattice plane (002 plane) as measured at a diffraction angle 2&#x3b8; of 22.6&#xb0; in X-ray diffraction analysis; and Iis a diffraction intensity of an amorphous moiety as measured at a diffraction angle 2&#x3b8; of 18.5&#xb0; in X-ray diffraction analysis, the process including the step of treating the cellulose-containing raw material using a media-type mill to reduce the cellulose I-type crystallinity of the cellulose to 33% or less, wherein the cellulose-containing raw material has a bulk density of from 100 to 500 kg/m.

Polyamine

The present invention provides an additive for asphalt which causes an improvement in anti-stripping effect of asphalt from aggregates, and exhibits the effect quickly. That is, the present invention provides an asphalt-additive composition comprising (A) a specific acidic phosphoric acid compound, and (B) at least one member selected from the group consisting of mineral oil, alcohol having 8 to 18 carbon atoms, carboxylic acid having 8 to 18 carbon atoms and triglyceride thereof; with the proviso that the amount of the (B) component is 25-400 parts by weight per 100 parts by weight of the (A) component.

Asphalt-additive composition

The present invention provides a liquid amine composition for an emulsifier for bitumen which can impart, to a bituminous emulsion, more excellent emulsifying stability and adhesive properties to aggregates than conventional products. The liquid amine composition for the emulsifier for bitumen of the present invention comprises (1) 5 to 70% by weight a monoamine having an aliphatic hydrocarbyl group of 8 to 22 carbon atoms, (2) 20 to 80% by weight of a polyamine having an aliphatic hydrocarbyl group of 8 to 22 carbon atoms, and (3) 10 to 75% by weight of an organic acid of 4 to 18 carbon atoms.

Liquid amine composition for emulsifiers for bitumen

The present invention provides an asphalt composition comprising an asphalt and antistripping additive comprising at least one of the compound having the formula (I), (II) or (III):
