The nucleophilicsubstitutionreactions of aromatic halides having electron-attracting groups on ortho or para position with various primary and secondary amines were accelerated by highpressure to give the corresponding N-substituted anilines in high yields. The bulkiness of amines affects its reactivity to lower the yields of the products. Although the secondary amines are usually less reactive

The presently disclosed and/or claimed concept(s) relates generally to a composition comprising a low molecular weight graft polymer. The graft polymer is a graft homopolymer, copolymer or terpolymer. Additionally, the presently disclosed and/or claimed inventive concept(s) relates to a scale inhibitor composition comprising the low molecular weight graft polymer. Furthermore, the presently disclosed and/or claimed inventive concept(s) relates to a process for preventing the deposition of scale from water or aqueous solution and a method for scale inhibition treatment of an oil or gas production well by using the low molecular weight graft polymer. The scale inhibitor is low corrosive for application in the oilfield.
