Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. Trimethyl borate is widely used in organic synthesis, semiconductors, flame retardants, coatings, pharmaceutical intermediates and other fields; trimethyl borate is modeled as a pure substance, and when modeling this substance the user needs to add a solvent of their choice in the model; this dataset includes the main raw and auxiliary materials, energy, waste and air emissions of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activity of this product includes raw material reaction, azeotrope formation, distillation purification and finished product collection and other process steps.
Activity Description
The production activities of this product include raw material reaction, azeotrope generation, distillation and purification, and finished product collection.
Process Description
Trimethyl borate has the chemical formula C3H9BO3 and CAS number 121-43-7. At ambient temperature, it is a colorless, transparent, volatile liquid with a mild ester-like odor. It is readily soluble in organic solvents such as methanol, ethanol, and diethyl ether, slightly soluble in water, and slowly hydrolyzes in water to form boric acid and methanol. It is chemically reactive, readily absorbs moisture from air, boils at approximately 68°C, and is flammable in the presence of open flames or high temperatures; combustion may produce toxic boron oxide fumes. It is mainly used in organic synthesis as a borane precursor and esterification catalyst and in the semiconductor industry to produce high-purity boron dopants for silicon wafers. It is also used in flame retardants and coating additives, as a derivatization reagent in analytical testing such as gas chromatography, and to a limited extent in the synthesis of pharmaceutical intermediates.

Technology comment
The mainstream technology for trimethyl borate production is the esterification of boric acid with methanol. The process is simple and yields high-purity product, accounting for over 90% of the domestic trimethyl borate market. This dataset represents this mainstream technology: boric acid and methanol are used as raw materials, which react in a reactive distillation column to produce trimethyl borate. Trimethyl borate and methanol form an azeotrope, which is then separated and purified via pressure swing distillation to obtain the final product. The main chemical reaction is: H3BO3 + 3CH3OH → B(OCH3)3 + 3H2O.
