What are the storage conditions of Sodium Thiomethoxide 20% in H2O?
Sodium hydride (Sodium hydride) is a 20% solution in water, and its storage conditions are very critical. This solution should be stored in a cool, dry and well-ventilated place. Because sodium hydride has certain chemical activity, if it is heated or wet, it may cause adverse reactions.
First, the temperature should be controlled in a lower range to prevent it from decomposing or accelerating chemical reactions due to high temperature. Under high temperature, sodium hydride may change with the composition of the water, affecting its chemical properties and purity.
Second, the environment must be kept dry. Too much moisture, in addition to affecting its concentration, may cause reactions such as hydrolysis, which will damage its original characteristics.
Third, good ventilation is also necessary. If there is no air circulation in the storage space, once the sodium hydride volatilizes or reacts to produce harmful gases, it is difficult to discharge in time, which not only endangers the environment, but also is harmful to the health of nearby people.
In addition, the storage container should also be carefully selected. Corrosion-resistant materials should be selected to prevent the container from reacting with the sodium hydride solution, causing the solution to be contaminated or the container to be damaged and leaked. Generally speaking, containers made of glass or specific plastic materials can be used for storage if there is no adverse reaction.
And the storage place should be kept away from fire sources, heat sources and strong oxidants. Because sodium hydride may have certain flammability or reducing properties, contact with fire sources and strong oxidants can easily cause fire or severe chemical reactions, endangering safety. Therefore, this solution is guaranteed to be stable during storage for subsequent use.

Sodium Thiomethoxide 20% in H2O What are the safety precautions during use
Sodium and sodium thiomethyl oxide (20% in water), when using it, many safety matters must be observed.
The first word is sodium, which is active in nature, burns dramatically in contact with water, and generates hydrogen gas. Therefore, when handling this thing, water vapor must be eliminated. Store sodium in kerosene or paraffin oil. When taking it, clip it with tweezers, cut it with a blade, and return the rest of the material to the original device quickly. If sodium touches the skin, quickly rinse it with a large amount of water, followed by boric acid solution.
As for the solution of sodium thiomethyl oxide, it is corrosive and can hurt the skin and eyes. When handling, it is advisable to wear protective clothing, gloves, and protective goggles. If the solution splashes on the skin, immediately rinse it with a large amount of water, and then dispose of it with an appropriate neutralizing agent; if it enters the eye, immediately buffer it with a large amount of water, and seek medical attention urgently.
Furthermore, when these two act, harmful gases may be generated, so the place of operation must be well ventilated, or a local exhaust device should be installed to drive away harmful gases and prevent their accumulation. And the equipment involved should be dry and clean, to prevent sodium and water from rushing, causing danger. During operation, strictly abide by the procedures, do not change the steps, doses, and pre-emergency plans to be prepared. In this way, the operation is safe and safe.

Sodium Thiomethoxide 20% in H2O
The process of preparing sodium and sodium thiomethoxy (containing 20% in water) requires delicate arrangement. First of all, the raw materials should be carefully selected. The sodium needs to be pure, and the water solution of sodium thiomethoxy needs to be precisely prepared.
At the beginning of the reaction, when the temperature is controlled properly, it should not be overdone. Because sodium is active, it will respond strongly in contact with water, so it is necessary to prevent its sudden changes during operation. Usually take an appropriate amount of water first, put it in a stable device, slowly add sodium thiomethoxy, and stir it well.
Then, with a special device, carefully add sodium to the mixture. When adding, it should be slow and even, so that the sodium and sodium thiomethoxyl are fully mixed, and the risk of boiling or splashing is avoided. In this process, continue to observe its temperature and response state, and adjust it in a timely manner.
After the reaction is completed, the product may need to be purified. It can be obtained by filtration, distillation, etc. to remove its impurities and obtain a pure product. However, when purifying, it is also necessary to abide by the procedures to ensure the quality of the product. In short, every step of preparing this agent requires caution. From the selection of raw materials to the control of the reaction, to the purity of the product, it is all about success or failure, and it must not be sloppy at all.

How does Sodium Thiomethoxide 20% in H2O react with other common chemicals?
Sodium thiomethanoxide (20% in water), a sulfur-containing compound, is active in nature and often involves many chemical reactions.
When it encounters halogenated hydrocarbons, it will initiate a nucleophilic substitution reaction. Halogen atoms in halogenated hydrocarbons are highly active, and sulfur atoms in sodium thiomethanoxide are nucleophilic. When the two meet, sulfur atoms attack the carbon atoms of halogenated hydrocarbons, and the halogen atoms leave to generate sulfur ether products. If it reacts with bromoethane, the bromine of bromoethane is replaced by the sulfur methyl of sodium thiomethanoxide to obtain ethyl thiomethyl ether.
When it encounters alters and ketones, a nucleophilic addition reaction occurs. The carbonyl group of aldehyde and ketone is polar, and the carbon is positively charged. The sulfur of sodium thiomeoxide attacks the carbonyl carbon nucleophilic, and the oxygen is negatively charged. After protonation and other steps, sulfur-containing alcohols are formed.
In acidic environments, there are also changes. Because the conjugated acidity of sodium thiomeoxide is not strong, it will protonate in contact with acid, and sodium thiomeoxide will be converted into thiomethanol. If the acidity is strong enough, thiomethanol may be further decomposed to produce products such as hydrogen sulfide.
In contact with oxidants, the valence state of sulfur in sodium thiomeoxide is variable. Common oxidants such as hydrogen peroxide can oxidize sulfur and increase the valence state of sulfur, and the products may be sulfoxides and sulfones.
In addition, if there are metal ions in the system, the sulfur atom of sodium thiomethyl oxide can be used as a ligand to complex with metal ions to form metal complexes, which may affect the chemical equilibrium and reactivity of the system.
When it encounters halogenated hydrocarbons, it will initiate a nucleophilic substitution reaction. Halogen atoms in halogenated hydrocarbons are highly active, and sulfur atoms in sodium thiomethanoxide are nucleophilic. When the two meet, sulfur atoms attack the carbon atoms of halogenated hydrocarbons, and the halogen atoms leave to generate sulfur ether products. If it reacts with bromoethane, the bromine of bromoethane is replaced by the sulfur methyl of sodium thiomethanoxide to obtain ethyl thiomethyl ether.
