The author of "Tiangong Kaiwu" is a great achievement of ancient science and technology. However, what is called "Ammonium+D-5-Bromo-6-Oxo-9-Bornanesulphonate" today, there was no such thing at that time, so it is difficult to describe its physical properties according to the method of "Tiangong Kaiwu". However, in today's scientific view, the properties of this thing may involve its morphology, melting and boiling point, solubility, etc.
It is probably at room temperature or in a solid state. Looking at its composition, it contains bromine, sulfur and other elements, and the structure is complex. Its melting and boiling point may vary depending on the force between molecules. If the intermolecular action is strong, the melting point and boiling point are higher. In terms of solubility, in polar solvents, because it contains polar groups, it may have a certain solubility; in non-polar solvents, it may be difficult to dissolve. And because it contains ammonium root, or has the characteristics of salt part, such as in aqueous solution or ionizable. But this is all speculated according to chemical principles, and experimental verification is needed to know the details.

The method of preparing ammonium-D-5-bromo-6-oxo-9-bornane sulfonate is quite complicated and requires detailed steps.
The starting material should be carefully selected. Among them, borneol derivatives need to be of good quality, and the choice of bromination reagents is also important. Common ones such as liquid bromine and N-bromosuccinimide can be considered for bromination reaction steps.
The bromination stage, the reaction conditions should be controlled. The temperature must be precisely controlled, usually at a moderate low temperature to prevent side reactions from clumping, but it should not be too low to slow down the reaction. The choice of solvent, when it is compatible with the reactants and reagents and is conducive to the reaction, such as halogenated hydrocarbon solvents such as dichloromethane and chloroform, is often a good choice. In this environment, the borneol derivative is brominated to obtain 5-bromo borneol derivatives.
Then, the oxidation step is crucial. To oxidize the specific group of 5-bromo borneol derivatives to carbonyl to form 6-oxo-5-bromo borneol derivatives. The oxidizing agent used in this step can be selected as Jones reagent, Dice-Martin oxidizing agent, etc. Factors such as pH and temperature of the reaction environment need to be carefully considered to ensure a smooth oxidation reaction and a pure product.
Then, the sulfonation reaction should not be underestimated. Select appropriate sulfonation reagents, such as concentrated sulfuric acid, chlorosulfonic acid, etc., to sulfonate the 6-oxo-5-bromo bornane derivatives, resulting in 5-bromo-6-oxo-9-bornane sulfonic acid derivatives. In this process, the reaction time, temperature and other conditions have a great impact on the yield and purity of the product.
Finally, the ammonium derivative is converted into ammonium-D-5-bromo-6-oxo-9-bornane sulfonate by the reaction of ammonium salt or ammonia gas under suitable conditions. After the reaction is completed, the target product with high purity is obtained by separation and purification methods, such as recrystallization, column chromatography, etc.
The whole preparation process requires fine operation and strict control of conditions in each step to obtain the ideal ammonium-D-5-bromo-6-oxo-9-bornane sulfonate product.

When using ammonium-D-5-bromo-6-oxo-9-bornane sulfonate, there are a number of precautions that need to be made clear.
First of all, safety is of paramount importance. This substance may have specific chemical activities or pose a potential danger to human health. When operating, be sure to strictly follow safety procedures and wear appropriate protective equipment, such as gloves, goggles, masks, etc., to prevent skin contact, eye contamination, and inhalation of dust or volatile gas. If you accidentally touch it, rinse it with plenty of water immediately and seek medical attention in a timely manner according to the specific situation.
Second, storage methods cannot be ignored. It should be placed in a cool, dry and well-ventilated place, away from fire, heat and incompatible substances. Improper storage may cause it to deteriorate, decompose, damage performance, or even cause safety accidents.
Furthermore, in the process of use, accurate measurement is crucial. Due to its special chemical properties, the amount of dosage has a great impact on the reaction process and product characteristics. When using precise measuring instruments, use them according to the exact dosage required for experiment or production, and must not be increased or decreased at will.
In addition, know its chemical properties so that it can be used reasonably. It is necessary to clarify its stability, reactivity, and compatibility with other substances under different conditions. This helps to design a suitable use plan, avoid adverse reactions, and improve the efficiency and effect of use.
Repeat, disposal must also be in compliance. After use, the remaining or generated waste should not be discarded at will. Proper disposal should be carried out in accordance with relevant environmental regulations to prevent pollution to the environment.
