Ginkgo biloba

Ginkgo biloba is loved by people because of its noble identity and unique posture. It is very resistant to natural growth conditions, but it looks very delicate when it is potted. Ginkgo biloba is a typical fleshy root plant. Its bast is hypertrophic and spongy. Its water absorption capacity is several times or even several times that of other tree species. For example, Ginkgo biloba is used to care for other tree species. It is difficult to survive in all directions. . Therefore, according to the growth characteristics of Ginkgo biloba, combined with my own conservation experience, the author summarized the following recipes and shared it with the readers here: The quantity of ginkgo was selected, and soil was used to avoid sticky soil. Susan cultivation was knowledgeable, and ventilation was strong. . The initial piles were mowed with water, and the new leaves were not very busy. Usually, the leaves were not sprayed with water, and the piles were most afraid of water dripping. It is not necessary to take special care. It is the amount of rainfall in the sky. When you find that the new leaves are wilting, do not mistake the water phase; if you add water, it will add frost to the snow. In this case, don't worry first. Leave the sun in the shade on the 3rd day. The bast is clear and the patient's border is clearer. The affected area has water-stained and rot-like appearance. Find the roots and identify the direction at the end; Potassium permanganate is washed first and then thiophanate-methyl; it is best to add a little bit of rooting agent to get the concentration and dose. Chemicals are different from each other, and the instructions are detailed; soaking time can be as long as one day and night. After the liquid is completely absorbed, the tung oil is applied over the wound; the remaining liquid is cleared and the pile is placed in the center. Susanna was deeply planted and high in cultivation, and the basin edged along with the height of the circle; here, to repeat, there is no need to water. Until the day of sprouting, the amount of water to be poured will be controlled; the pile will look like a pot, and the pot will change its appearance.

Organic Intermediate

Organic intermediate is an important raw material in chemical production. It is an intermediate step or intermediate product in the manufacture of various organic chemicals. Organic intermediates are often key components in organic synthesis and can be converted into the final target product through further reactions.Here are some common organic intermediates:5-Heptylresorcinol,2-Methylimidazole,Tetrabutylammonium bromide,Benzaldehyde,Sodium p-toluenesulfonate,Ethyl difluoroacetate,2-Imidazolidone hemihydrate,Guanidine Hydrochloride,Bromoacetaldehyde diethyl acetal etc.

These organic intermediates are key steps and raw materials in chemical synthesis, and they undergo further reactions, transformations and purification to obtain the final organic chemicals, such as drugs, dyes, plastics, coatings, etc. The supply and production of organic intermediates are essential for the development of the chemical industry.

Intermediates in organic chemistry are a class of compounds between the starting material and the final product in the process of organic synthesis.
They usually have a specific chemical structure and reactivity and act as a bridge in organic reactions. The existence of intermediates in organic chemistry makes the synthesis of complex organic molecules possible.
Some common organic chemical intermediates include: carbocation, carbanion, free radical and so on. Carbocation is a kind of positively charged carbon atom with high reactivity and is an important intermediate in many organic reactions, such as electrophilic substitution reactions. Carbanion is a negatively charged carbon atom, often used in nucleophilic substitution and addition reactions. Free radicals are atoms or groups that contain unpaired electrons and play a key role in free radical reactions.
The properties and reactivity of organic chemical intermediates have important effects on the route and efficiency of organic synthesis. Through reasonable selection and use of intermediates, the efficient synthesis of target products can be achieved. Their preparation and application is one of the important contents of organic chemistry research.
In industrial production, organic chemical intermediates are also a key link in the synthesis of many chemical products and drugs. Their in-depth research and development can help improve production efficiency, reduce costs, and promote the birth of new organic compounds and materials.
