Dear Mohamed H. Kalaba, the simplest way is to perform the reaction under Microwaves instead of a conventional water bath. Please have a look at the following document, you may search for similar studies. My Regards

Acid concentration: The concentration of the acid used in the deacetylation step can affect the rate of deacetylation. Higher concentrations of acid may lead to faster deacetylation, but may also result in a lower degree of deacetylation. pH: The pH of the deacetylation solution can also influence the rate of deacetylation. Lower pH values may result in faster deacetylation, but may also lead to a lower degree of deacetylation. Agitation: Agitation of the deacetylation solution can help to accelerate the deacetylation process by increasing the rate of mass transfer. This can be achieved by stirring the solution or using a mechanical agitator. Particle size: The particle size of the chitosan can also affect the rate of deacetylation. Smaller particle sizes may lead to faster deacetylation due to increased surface area.
There are a few other factors that can affect the deacetylation step in the preparation of chitosan from shrimp:
It is important to carefully consider all of these factors when optimizing the deacetylation step in chitosan preparation, as they can all play a role in determining the final product quality.
