The present invention provides a method for producing highly reactive polyisobutylene by liquid phase polymerization of isobutylene or isobutylene containing feed stock, wherein at least 70 mole % of polymer chains in the polyisobutylene have exo olefin end groups. Further, the present invention provides a catalyst composition for polymerization, comprising of a Lewis acid complexed with at least two Lewis bases selected from sterically hindered ether and linear dialkyl ether; or a Lewis base complexed with at least two Lewis acids selected from aluminium halides mixture. The present invention additionally provides that Lewis acid with Lewis bases mixture or Lewis base with Lewis acids mixture constituting the catalyst show synergistic effect resulting in high isobutylene conversion and production of polyisobutylene having high exo olefin content, while maintaining desired molecular weight range of 250-10000 Dalton.

The present invention relates to a method based on proton NMR technique to differentiate genuine and spurious Hand-rub formulations. This method identifies and estimates all four components present in WHO-recommended Hand-rub formulations. Further, this method also identifies the presence of non-recommended/additional components present in WHO-recommended Hand-rub formulations. The method described in this invention utilizes experimental parameters and derived equations to quantify all four components in just fifteen minutes without using any organic solvents.
