In the last decade, several studies focused on clarifying this problem by modifying shellac molecules, including salt formation [3], partial hydrolysis [4] and modification the structure of shellac by esterification with cyclic anhydride [5].
The motivations for the development of dry media reactions in chemistry are economic, to ease purification, promote a high reaction rate, to be environmentally friendly and to simplify the reaction procedure [6].

Starch microsphere is a novel material [7] with tremendous development potential in the field of absorbency and sepatibration of harmful compounds or wastewater treatment process for its irregular appearance, uniform size, suitable swelling, three-dimensional network structure, suitable shell pore diameter and specific surface area, good mechanical intensity and especially for its good biocompale and biodegradable, and it couldn’t bring any secondary pollution to environment.

Presently, the cellulose chemistry in ionic liquids has been one of the hot topics in current research and development of ionic liquids [3, 5-6].
The appearance of ionic liquids also provides a broader scope for the development of cellulose chemistry.
The phase separation occurred when the contents were beyond 6% which were wrecked the ordered structure of the blend membranes with the drop of the degree of crystallization.

This model can explain almost all of the results with a knowledge of radiation chemistry.
Sometimes the spur model can give new information for radiation chemistry [see pp.129 of ref.6, 8].
µ is the magnetic moment of the electron and 0 h is the hyperfine structure splitting between o-Ps and p-Ps in vacuum.
