Abstract: A polypropylene resin composition which may prevent deterioration of properties due to moisture. The polypropylene resin composition has low surface energy, and thus may increase chemical stability against external factors. Further, a molded product including the polypropylene resin composition may have low ion elution ability, which may be an important requirement, and may achieve high weight reduction.

Abstract: The present invention relates to a process for preparing dioxolane by reacting ethylene glycol with an aqueous solution of formaldehyde in the presence of an acid catalyst. The raw product comprising water, dioxolane and methanol is fed to a phase separation unit (20) wherein an organic extracting agent is present. An organic fraction stream from the phase separation unit is transferred to an upper part of a purification column (30) from which dioxolane is withdrawn as a bottom product while the distillate stream of the purification column is recycled to the phase separation unit. An aqueous fraction stream from the phase separation unit is transferred to a waste water column (40), withdrawing a waste water stream from the bottom of the waste water column, recycling a distillate stream (42) from the waste water column to the phase separation unit, and withdrawing a side stream (43) containing methanol from a stage below the feed stage of the waste water column.
