  In the preparation of ethylene glycol by reacting methanol, formaldehyde and an organic peroxide, improved yields of ethylene glycol are achieved by the reaction of portions of the total amounts of formaldehyde and peroxide to be reacted with methanol. Formaldehyde and peroxide are incrementally added to a liquid medium containing methanol in controlled amounts during the reaction to permit conversion of each portion of said formaldehyde and peroxide reactants prior to the next addition. The portions are added such that the concentration of glycol in the reaction medium to which a later portion is added is greater than that to which an earlier portion is added. The reaction is continued until all the formaldehyde and peroxide has been incrementally added to the reaction medium and subjected to reaction conditions for a suitable period of time.

  A lubricating oil additive containing at least one acrylic block copolymer having a weight-average molecular weight of 10,000 to 1,000,000 and a molecular weight distribution [ratio of weight-average molecular weight (Mw) to number-average molecular weight (Mn), i.e. Mw/Mn ratio] of 1.5 or below and lubricating oil compositions containing the additive. The lubricating oil additive exhibits a thickening effect higher than those of conventional acrylic lubricating oil additives and can improve the viscosity index of lubricating oil even when added in a small amount. Further, the additive can also improve the low-temperature characteristics, flow characteristics, and shear stability. The lubricating oil compositions enable energy saving and can lengthen the lifetime of lubricating oil and reduce the load on the global environment.
