Manufacturing of para toluene sulfonic acid engineering essay

Moreover, the sulfonated product is almost free of coloration and is therefore usable for various applications without necessitating purification. Examples of other substituents which may be present conjointly with these substituents are halogen atoms, and carboxyl, aldehyde, azo, carbonyl, sulfonic acid and like groups.

The amount of solvent to be used, which differs with the compound to be sulfonated and is suitably determined, is usually about 1 to about 20 times the amount by weight of the sulfonating agent.

STR3 wherein R1, n and m are as defined above, R2 is an aromatic ring having or not having a substituent, H in R2 --H is a hydrogen atom attached directly to a carbon atom forming the aromatic ring, and p is the number of sulfonic acid group s introduced into the aromatic ring and is usually an integer of 1 or 2.

Polymers for Advanced Technologies Research Interests: Subsequently, a sample was collected from the reaction mixture and analyzed by the HPLC external standard method with the result given below. The intrinsic physical parameters of the composites were used as a database for the optimization calculation.

Typical examples of such compounds are given below. Time Conversion of productEx. My product have surfactant which making natural process, chemical,ester and biodiesel.

During process of decoration spot of application of background engobe is restricted by at least one local spot, formed by one closed circuit of cutting, at least, one layer of background engobe of the color contrast to that of the foundation is applied on the foundation; there after the product is dried and texturised by cutting of the background layer with applied engobes uncovering foundation of the product; there after received decorative elements are painted with multicolored engobes and refreshed by additional cutting getting as a result corresponding ceramic product.

Our moto is to give the complete satisfaction our customers work as bridge between supplier customer.

Jiangsu Bohan Industry Trade Co. A sulfonating process as defined in claim 2 wherein m is 1. For example when a sulfonated compound having one sulfonic acid group introduced therein is to be obtained, the sulfonating agent is used in an amount, calculated as the number of sulfonic acid groups therein, of 0.

It seems that the graph shows best fit to the experimental data. Preferable aromatic amine compounds are anilines or naphthylamines having or not having the above substituent.
