Nitrous oxide N2O has wide downstream uses and the productivity of domestic high-purity products needs to be improved.

Nitrous oxide, with the chemical formula N2O, also known as nitrous oxide, is a colorless and sweet gas. Nitrous oxide is slightly soluble in water, soluble in ethanol, ether, concentrated sulfuric acid, etc. It is stable at room temperature and is an oxidant that can burn under certain conditions. Nitrous oxide has a mild anesthetic effect and can make people laugh, so it is also called laughing gas. Nitrous oxide has a wide range of downstream uses.

Inhaling nitrous oxide can cause people to lose their sense of pain while still being conscious. Therefore, it was used as an anesthetic in the medical field in the early days. It can be used in the field of oral medicine and can also be used in the field of surgery in conjunction with other anesthetics. However, inhaling high concentrations of nitrous oxide can cause suffocation, and long-term inhalation can cause syncope, anemia, hypertension, heart disease and other diseases, and damage the central nervous system. Therefore, nitrous oxide is basically no longer used for anesthesia at this stage. Because nitrous oxide is highly toxic and can be used as a drug, its production and sales are strictly controlled.

Nitrous oxide can be used in the field of pipeline leakage detection and can be used as an analysis and determination reagent; it can be used as a preservative in the field of anti-corrosion of organic chemicals; it can be used as a combustion accelerant to speed up fuel combustion and increase the speed of vehicle engines; it can be used As an oxidant, it is used in the field of rocket fuel manufacturing; it can be used as a suspending agent, foaming agent, and sealant in the food, beverage, and dairy industries; it can also be used in pharmaceuticals, cosmetics and other industries.

According to the “2021-2025 Nitrous Oxide (N2O) Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research CenterShows that high-purity nitrous oxide can be used in the electronics industry. It is an electronic gas with a purity requirement of 99.999% (5N) or above. High-purity nitrous oxide is mainly used in chemical vapor deposition (CVD). The manufacturing of dielectric films for semiconductor optoelectronic devices is its main application field. It can be used to prepare doped silicon dioxide films, silicon nitride masking films, and material surface passivation films. , anti-reflection and anti-reflection coating, etc. The purity and impurity content of high-purity nitrous oxide directly affect the performance, quality and yield rate of semiconductor devices, and the technical barriers are high.

Globally, the production capacity of nitrous oxide, especially high-purity nitrous oxide, is mainly concentrated in the hands of overseas giants. The representative manufacturers are mainly Germany’s Linde Group (Linde Group), Germany’s Messer (Messer), and Europe’s SOL Group, Praxair, Air Products, etc. Driven by the growing downstream demand, my country’s nitrous oxide production capacity has begun to increase. However, due to technical limitations, the demand for high-purity products is highly dependent on external sources.

Industry analysts said that in many fields such as industrial production, agricultural production, wastewater treatment, and automobile exhaust, emissions of Nitrous oxide exhaust gas. Nitrous oxide is a greenhouse gas that can destroy the ozone layer. Its annual emission is lower than carbon dioxide, but the warming potential of a single molecule is much higher than that of carbon dioxide. Therefore, the reasonable recycling and reuse of nitrous oxide has attracted attention, and related companies have greater potential. Development potential. In my country, Shandong Jinbo Environmental Protection Technology Co., Ltd., Suzhou Jinhong Gas Co., Ltd., China Shenma Group Co., Ltd., etc. are all carrying out nitrous oxide recovery and reuse projects.
