Butyldiglycol (DEGB) is a colorless, volatile liquid with a slight aromatic odor. Its chemical formula is C8H18O3, which is an important organic solvent. Due to its unique physical and chemical properties, it has a wide range of applications in coatings, dyes, resins, and other fields.
Solvent
Dissolving resin and natural rubber: It is a good solvent that can dissolve various resins and natural rubber, such as epoxy resin, polyurethane resin, acrylic resin, etc. Adding it to the coating can improve its solubility, make it more uniform, and thus enhance the performance and quality of the coating.
Adjusting volatilization rate: With a lower boiling point and a higher volatilization rate, it can adjust the volatilization rate of coatings or paints to make them more controllable.
This is very important for construction in humid or rainy weather to avoid the problem of paint drying too slowly or too quickly.
Volatility: It has low volatility and can reduce the impact of coatings or paints on the environment during use.
Improve leveling: With lower surface tension, it can improve the leveling of coatings or paints and reduce surface defects such as shrinkage. This is very important for the decorative effect of coatings, as it can ensure the smoothness and flatness of the coating.
Antistatic performance: It has good anti-static performance, which can reduce the electrostatic adsorption on the surface of coatings or paints, making the coating smoother.
Adjusting odor: It has a slight aromatic odor and can adjust the odor of coatings or paints to make them more pleasant.

According to literatures and patents, there are mainly two ways to synthesize butyldiglycol:
Ethylene glycol butyl ether is prepared from ethylene oxide and butanol:
CH3CH2CH2CH2OH→HOCH2CH2OCH2CH2CH2CH3
Zhang Mu used this reaction route to prepare ethylene glycol butyl ether in the supplement of petrochemicals Vol. 37 in 2008. In this method, ethylene oxide and n-butanol were used as raw materials, and heteropoly acid was used as catalyst to prepare ethylene glycol butyl ether at low pressure of 70-120 ℃. The selectivity of ethylene glycol butyl ether was up to 75%. However, this reaction has many by-products and is a strong exothermic reaction. The reaction is not easy to control. The product contains a large amount of diethylene glycol butyl ether, triethylene glycol butyl ether, tetraethylene glycol butyl ether, pentaethylene glycol butyl ether, hexaethylene glycol butyl ether and the corresponding diether. Subsequent separation is difficult and energy consumption is high.
Synthesis of ethylene glycol butyl ether from synthesis gas and formaldehyde
CO+2H2+HCHO+CH3CH2CH2CH2OH→HOCH2CH2OCH2CH2CH2CH3+H2O
In the United States Patent 4071568, Kurashiki, a Japanese chemist, introduced the synthesis of ethylene glycol butyl ether with synthesis gas, formaldehyde and n-butanol as raw materials and cobalt as catalyst under the extremely high pressure of 100-250 ℃, 50MPa, of which the yield of ethylene glycol butyl ether is the highest, 55.6%. However, the disadvantages of this method are that the reaction needs to be carried out under extremely high pressure, requiring 500 atmospheres, requiring extremely high requirements for reaction equipment, and the preparation process of the cobalt catalyst for the reaction is cumbersome and cannot be reused, so it is not used in large-scale industrial production.
A new synthesis route of ethylene glycol butyl ether, the first step is the highly selective synthesis of butoxymethoxymethane from methylal and butanol; The second step is the directional carbonylation of butoxymethoxymethane to produce methyl butoxyacetate; The third step is the hydrogenation of methyl butoxyacetate to produce ethylene glycol butyl ether and methanol. Among them, the third step of ester hydrogenation reaction is very easy and has high selectivity. The second step is the directional carbonylation reaction. It has been reported in the literature and patents that the carbonylation of methylal produces methyl methoxyacetate with high selectivity. Only for the synthesis of the first reaction raw material methoxybutoxymethane, there is no report on the specific synthesis method and route on SciFinder.
