Introduction
1,3,2-Dioxazoliphene-2,2-dioxide (DOPO) is an organic compound with important application value. The following is an introduction to the nature, use, manufacturing method and safety information of DOPO:Quality:- DOPO is a solid crystal with a white or yellowish color.- It has high thermal stability and chemical resistance.- DOPO is stable in air but easily soluble in organic solvents.Use:- DOPO is an additive widely used in flame retardant materials.- Due to its unique structure, DOPO can effectively improve the flame retardant properties of polymers.- It can be used as a flame inhibitor in fields such as electronics, plastic materials, textiles and coatings.- DOPO can also be used as a reagent in organic synthesis reactions.Method:- DOPO is a complex preparation method and is usually obtained by multi-step reactions.- A common preparation method is to react dioxazole and thiophene in the presence of oxygen to form DOPO.- The process of preparing DOPO requires strict temperature and reaction conditions to ensure high yields and purity.Safety Information:- DOPO is relatively secure, but there are still the following issues to be aware of:- DOPO may produce toxic gases at high temperatures, so it is necessary to avoid prolonged exposure to high temperatures.- When using DOPO, follow appropriate laboratory practices and safety measures, such as wearing protective gloves and glasses, and ensuring adequate ventilation.
Application
Ethylene glycol cyclic sulfate (1,3,2-Dioxathiolane 2,2-dioxide, DTD) is a high-purity cyclic sulfate ester. As a premium electrolyte additive, it is preferentially reduced to form a stable, low-impedance solid-electrolyte interphase (SEI) on graphite anodes, significantly enhancing capacity retention, cycle life, and low-temperature performance in lithium-ion batteries for EVs, portable electronics, and grid storage. In organic synthesis, it acts as a powerful alkylating and hydroxyethylation reagent for producing pharmaceutical intermediates, antihypertensive agents, and specialty heterocyclic compounds. It is also a key precursor for monodisperse polyethylene glycols (M-PEGs), flame retardants, gelatin hardeners, and novel double surfactants.
