Production Method of DPNB Dipropylene glycol monobutyl ether:

Ethylene oxide process: This method is one of the most commonly used synthesis processes. First, ethylene oxide is mixed with hydrogen and then hydrogenated under a catalyst to produce propylene glycol. Then, in the presence of a catalyst, dipropylene glycol was REDOX with butyl lithium to obtain dipropylene glycol monobutyl ether. 

Direct esterification method: This method is the direct esterification reaction of propylene glycol and butyric anhydride under the action of a catalyst to obtain propylene glycol mono butyl ether. This method avoids using hydrogen as a catalyst, reducing environmental pollution and safety risks. However, due to butyric anhydride's corrosive and toxic nature, it is necessary to operate in a specific fume hood to ensure the operator's safety.

The condensation method uses a reaction to prepare propylene glycol mono butyl ether. First, sodium tripolyphosphate or sodium tetraphosphate is reacted with propylene glycol to form a hexametaphosphate compound. This compound is condensed with butyric anhydride to obtain dipropylene glycol monobutyl ether. This method has better product purity and yield. Still, it needs to use more toxic and harmful substances such as inorganic phosphorus compounds and organic acid anhydride, which has potential risks to the environment and human health.

Hydrolysis is to prepare propylene glycol mono butyl ether by hydrolysis reaction. First, propylene glycol and cresol were esterified under acidic conditions to produce propylene glycol mono-cresol ester. Then, the esterified substance is hydrolyzed under alkaline conditions to obtain dipropylene glycol monobutyl ether. This method has better product purity and yield. Still, it needs to use more toxic and harmful substances and dangerous chemicals, potentially damaging the environment and human health.

The biological fermentation method is to prepare propylene glycol monobutyl ether by biological fermentation technology. First, glycerol is fermented by microorganisms such as bacteria or yeast to produce propylene glycol. Then, propylene glycol is REDOX with butyric anhydride to obtain propylene glycol mono butyl ether. This method has the characteristics of green environmental protection, avoiding using toxic and harmful chemicals, catalysts, and other processes while reducing production costs and improving product quality.
