Effect of reaction time, reaction temperature, pH, amount of sodium periodate, and amount of ethanol on the aldehyde content of DCLGG.

(a) Reaction conditions: reaction temperature = 40°C, amount of sodium periodate = 30%, amount of ethanol = 77%, and pH = 4

(b) Reaction conditions: reaction time = 3 h, amount of sodium periodate = 30%, amount of ethanol = 77%, and pH = 4

(c) Reaction conditions: reaction time = 3 h, reaction temperature = 40°C, amount of sodium periodate = 30%, and amount of ethanol = 77%

(d) Reaction conditions: reaction time = 3 h, reaction temperature = 40°C, pH = 4, and amount of ethanol = 77%

(e) Reaction conditions: reaction time = 3 h, reaction temperature = 40°C, pH = 4, and amount of sodium periodate = 30%
