| 摘要 |
Alkenylsuccinic anhydride is reacted with an amino alcohol, such as tris(hydroxymethyl)aminomethane, to provide intermediate reaction products from which novel derivatives are obtained by reacting the said intermediate product with boric acid or organoborates, organophosphonates and aldehydes. The intermediate reaction product prepared from tris(hydroxymethyl)aminomethane contains unexpectedly an oxazoline component when the reaction is carried out at 175 DEG C or below, preferably 100 DEG to 175 DEG C. The reaction products and their derivatives are particularly useful in lubricants, fuels or other industrial fluids as detergents. |
