Method for synthesis of tetrazolylacetic acid using hydrazine hydrate method

Abstract

The invention discloses a method for synthesis of tetrazolylacetic acid using a hydrazine hydrate method. The tetrazolylacetic acid is prepared from the raw materials of triethylorthoformate, glycine,hydrazine hydrate, sodium nitrite and the like. According to the method for synthesis of tetrazolylacetic acid using the hydrazine hydrate method, the processing route of a traditional azide ester method that sodium azide is adopted as a raw material to prepare the tetrazolylacetic acid is abandoned, the safety of the production technology is improved, the production cost is low, no waste water or waste gas is generated in the whole technology, the method accords with the production requirement of green chemical, co-produced salt sodium sulfate can be sold out directly, and the production cost is further lowered. According to the method for synthesis of tetrazolylacetic acid using the hydrazine hydrate method, the synthetic route is simple, the product purity is high, the maneuverabilityand the repeatability are high, and industrial production is facilitated.

AI Technical Summary

Benefits of technology

This patented technology describes making certain types of compounds from aminonitrogenic acids called tetraazoleacetic acid (TAA). These TAA are used as starting materials because they have several advantages compared to other methods such as nitrilotriacetonates. They also improve their overall efficiency during manufacturing processes while reducing its risk of explosions due to flammable substances produced when exposed at elevated temperatures. Overall, this new approach simplifies the way these molecules were made up without generating any harmful wastes that could affect environmental quality standards.

Problems solved by technology

This patented describes different ways to produce tetrazoline (TZ) that could have various benefits like reducing drug resistance issues caused by microorganisms called MRSA. However, current techniques require expensive starting products from multiple sources and involve complicated steps during their formation processes. Additionally, these existing technologies often result in poor yields and increased costs associated with disposable plastic containers containing residual amounts of impurity compounds.
