About ETB 2-Tert-Butoxyethanol:  

Ethylene glycol monobutyl ether (2-Butoxyethanol) is an organic compound with the formula C6H14O2. The boiling point of ethylene glycol monoethyl ether is higher, about 188 ° C and the freezing point is lower, about -60 ° C.

Ethylene glycol monoethyl ether is a common organic solvent. Because of its good solubility and stability, it is widely used in producing paints, inks, adhesives and other fields. It can effectively dissolve various resins and polymers, thereby improving the quality and performance of products. In addition, ethylene glycol monoethyl ether also has certain corrosion resistance and anti-rust properties and can be used as a protective agent for metal surfaces.

When using ethylene glycol monoethyl ether, paying attention to its toxicity and irritation is necessary. Although the toxicity of EGDM is relatively low, long-term exposure or inhalation of high concentrations of EGDM may cause certain irritation and damage to human eyes, respiratory tract and other organs. Therefore, when using ethylene glycol monoethyl ether, you need to take appropriate protective measures, such as wearing protective clothing, gloves, masks, etc., to reduce harm to the body.

In addition, ethylene glycol monoethyl ether also has a certain degree of flammability, so it is necessary to pay attention to fire prevention measures during use. However, it should be noted that it can not be mixed with strong oxidants or alkali substances so as to avoid chemical reactions causing danger.

Production Method of  ETB 2-Tert-Butoxyethanol:

Alcoholysis method:

Alcoholysis is one of the main methods to produce ethylene glycol monoethyl ether. In this method, ethyl alcohol and monochloromethane were used as raw materials to produce methoxyethanol through an esterification reaction, and then glycol monobutyl ether was obtained through a hydrolysis reaction. The specific steps are as follows:

(1) Esterification reaction: ethanol and methyl chloride are esterified under the action of a catalyst to produce methoxyethanol. This step is a reversible reaction, and the reaction temperature and pressure need to be controlled to make the reaction proceed in the direction of the formation of methoxyethanol.

(2) Hydrolysis reaction: methoxy ethanol and water are hydrolyzed under the action of a catalyst to produce ethylene glycol monoethyl ether. Hydrolysis reaction needs to control the reaction temperature and pressure, and attention must be paid to prevent the occurrence of side reactions.

(3) Rectification: distillation of the hydrolysis reaction products to separate glycol monoethyl ether. The rectification aims to remove by-products and impurities and obtain high-purity ethylene glycol monoethyl ether.

Ethylene process:

The ethylene process is another method for producing ethylene glycol monoethyl ether. Ethylene and ethylene oxide were used as raw materials, ethylene glycol was formed by addition reaction, and then ethylene glycol monobutyl ether was obtained by substitution reaction with methyl chloride. The specific steps are as follows:

(1) Addition reaction: ethylene and ethylene oxide are added under the action of a catalyst to produce ethylene glycol. The addition reaction must be carried out under certain temperature and pressure conditions to control the reaction speed and selectivity.

(2) Substitution reaction: ethylene glycol and monochloromethane are substituted under the action of a catalyst to produce ethylene glycol monobutyl ether. The conditions and selective control of the substitution reaction are similar to that of the addition reaction, but attention should be paid to preventing the occurrence of side reactions.

(3) Rectification: distillation of the product of the substitution reaction is carried out to separate glycol monoethyl ether. The rectification aims to remove by-products and impurities and obtain high-purity ethylene glycol monoethyl ether.

Transesterification method:

Transesterification is another feasible method for producing ethylene glycol monoethyl ether. The method uses methyl ester and ethanol to produce ethylene glycol monoethyl ether by transesterification reaction. The specific steps are as follows:

(1) Transesterification reaction: methyl ester and ethanol are transesterification reactions under the action of a catalyst to produce ethylene glycol monoethyl ether. Transesterification reaction must be carried out under certain temperature and pressure conditions, and the reaction speed and selectivity are controlled.

(2) Rectification: distillation of the transesterification reaction products to separate glycol monoethyl ether. The rectification aims to remove by-products and impurities and obtain high-purity ethylene glycol monoethyl ether.
