The synthesis method of 1-fluoro-3-isothiocyanate phenyl ester, although the ancient book "Tiangong Kaiwu" does not directly record the synthesis of this substance, the chemical process idea contained in it may be useful for reference.
In ancient chemical industry, natural materials were often the starting point. To synthesize 1-fluoro-3-isothiocyanate phenyl ester, you can first find natural substances containing benzene rings, such as some aromatic plant extracts, and purify benzene derivatives by distillation and extraction.
One method can be started from fluorine-containing benzene derivatives. Find fluorine-containing ores, roasting and other processes, so that fluorine elements are free in a suitable form and react with benzene derivatives under specific conditions. If at high temperature and there is a catalyst, fluorine-promoting atoms replace specific hydrogen atoms on the benzene ring to obtain 1-fluorobenzene derivatives.
Next, isothiocyanate is to be introduced. Ancient Chemical Industry, mostly using natural materials such as sulfur and cyanide to make related reagents. Sulfur can be co-heated with nitrogen-containing materials to form sulfur-containing and nitrogen-containing intermediates, and then reacted with 1-fluorobenzene derivatives. If the intermediate is fully contacted with 1-fluorobenzene derivatives under mild heating and appropriate solvents, through substitution reaction, isothiocyanate is introduced at the third position of the benzene ring, and then 1-fluoro-3-isothiocyanate is obtained.
When operating, pay attention to the heat and material ratio. If the heat is too strong, or the reaction is excessive, the product is impure; if the material ratio is improper, it is difficult to meet expectations. And the cleanliness of the reaction environment and the material of the equipment used are all related to the success or failure of the synthesis. Although the ancient process is different from today, the spirit of careful operation and exploration of physical properties can be used as a reference for the synthesis of 1-fluoro-3-isothiocyanate phenyl ester.

1-Fluorophenyl-3-isothiocyanate is a chemical substance. When storing and transporting, many matters must be paid attention to.
Let's talk about storage first. This material is lively and should be placed in a cool, dry and well-ventilated place. Because it is sensitive to temperature and humidity, it may deteriorate in a high-temperature and humid place. The temperature of the warehouse should be controlled within a specific range, and it should not be too high to prevent it from reacting. And it should be kept away from fires and heat sources. Because it is flammable, it may encounter open flames, hot topics, or risk of burning. Furthermore, it should be stored separately from oxidizing agents, acids, alkalis, etc., because of its active chemical properties, contact with their substances, easy to cause chemical reactions, endangering safety. Storage places also need to be equipped with suitable materials to contain leaks, in case of leakage, can be disposed of in time.
As for transportation, it should not be neglected. Before transportation, it is necessary to ensure that the packaging is complete and sealed to avoid leakage during transportation. During transportation, the vehicles used should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. During driving, it should be protected from exposure to the sun, rain and high temperature. Road transportation, follow the prescribed route, do not stop in residential areas and densely populated areas. Railway transportation, also need to comply with relevant regulations to ensure transportation safety. When loading and unloading, the operator must strictly follow the operating procedures, pack and unload lightly to prevent damage to the packaging and containers and cause material leakage.
In short, the storage and transportation of 1-fluoro-3-isothiocyanate phenyl ester, every step is related to safety, and must be treated with caution.
