The reaction can generate g-octolactone. The reaction formula is as follows:

1. Condensation with propylene glycol to prepare 2-hexyloxy-1-propanol:

2. Prepare gamma-octolactone by responding 2-hexyloxy-1-propanol with acid and base:

HOCH2CH2O( CH2) 5CH3 + HX → HOCH2CH2O( CH2) 5CH2X + H2O
HOCH2CH2O( CH2) 5CH2X + NaOH → HOCH2CH2O( CH2) 5CH2O-Na+ + WATER + X.
