Method of reducing flock during alkoxylation

A method of reducing flock during alkoxylation comprising:

• providing a feed receptacle comprising alkylene oxide comprising a liquid fraction and a vapor fraction;
• diffusing said alkylene oxide consisting essentially of at least a portion of said vapor fraction from said feed receptacle to said reaction vessel;
• and
• reacting a polyalkylene glycol with said portion of said vapor fraction, producing an alkoxylation product;
• wherein said alkoxylation product comprises a reduced amount of flock compared to a quantity of flock produced when said liquid fraction is withdrawn from said feed receptacle and reacted with said organic compound.
