    摘要： This invention relates to an additive package containing an organic solvent, a detergent additive and a reaction product mixture obtained by reacting a carboxylic acid compound of formula (I): R1COOR2 with an alkanol amine of formula (II): NHR3R4 to form a reaction product containing a polysubstituted alkanol amine derivative, where the reaction is performed by: (a) heating the carboxylic acid of formula (I) to a first temperature; (b) adding thereto the alkanol amine of formula (II) under controlled conditions avoiding an increase of temperature above the first temperature range; (c) maintaining temperature in the first temperature range; and (d) increasing the temperature of the reaction mixture to a second temperature in a second temperature range of 160 to 210° C. and allowing further reaction of residual free carboxylic acid molecules with any reactive group in the reaction mixture.
