Most products of Fluorine-Containing Benzaldehyde are a pale yellow liquid. They are playing an important role in fine chemical intermediates, is used as the main raw material for the synthesis of a variety of pesticides, pharmaceuticals, surfactants, polymer monomer mildew. As used in medicine synthesis antihypertensive drugs, antipyretic analgesic anti-inflammatory drugs, anti-cancer drugs, muscle relaxation drugs for synthesizing fluorine cypermethrin, fluorine chlorobenzene daisy cool in pesticides, fluoride and styrene, wherein the polymer of styrene monomer to fluorine can be widely used in the manufacture of the recording material, a thermoplastic resin coating, liquid crystal materials. Currently new miticide is effective pesticide products which is the main raw material of Fluorine-Containing Benzaldehyde.

In recent years, with the adjustment of the agricultural structure, ginseng has developed rapidly in low mountain areas and has become an important road for increasing farmers' income. The dry products of Dangshen are dry, fatty, yellowish-white, shiny, and translucent. If you are unfamiliar with the processing method, the original thick and fresh, fresh rhizomes will become dark and hard-hearted and will be reduced to inferior products. Therefore, we must pay attention to the processing of tail ginseng.
Timely mining. It is usually harvested after the third year after cultivation and also harvested in the second year after planting. The specific harvest time cannot be too early or too late. Premature accumulation of nutrients is not enough, excess water, thin after drying, not strong. Late due to the influence of low temperature environment, part of the starch is converted into soluble sugar and consumed, resulting in less starch, light meat, and poor quality. Specifically, the harvest time for Miao Ding is set. When the local part of the crop is withered normally, it is suitable for harvesting. In the middle and lower reaches of the Yangtze River, it is generally appropriate to harvest after frost, that is, in late October and early November. Cut off the stems and leaves first, then dig. During the excavation, roots should be prevented from breaking or being damaged. After excavation, the mud and fibrous roots should be removed by hand, and the water should be transported back after the moisture is lost. This will prevent it from being broken, so as not to reduce the grade. The average yield of fresh stems is 2000-2500 kilograms, and the dry weight is 700-800 kilograms. There are two ways to process it.
Drying method. The tail ginseng was graded according to size, disease stems, stems, stems, deformed stems, and black stems were removed. Choose sunny days to spread the sun, such as rain after harvesting, to spread thin, to prevent heap rot, and then sunny after the sun. Spread in the sun, drying, every half-day drying, to flip once and rub it by hand, after the evening airing back. This is repeated many times until the rhizomes are completely softened. There is no hard heart in the stems and the color yellow is shiny. If the number is too large, it is not convenient to rub it by hand. After the sun, bamboo basket collision method can be used instead of hand rubbing method. That is, the tail of the sun is put into the bamboo basket, and the front and back are strongly crushed, so that repeated friction and collision between the tail and the bamboo basket become weak. Then use a black film bag to hold the mouth tightly and place it in the sun for 2-3 hours. At night, piling it together overnight. The next day, pour it out and dry it until you feel it with your hands. It is not easy to break. can.
Steaming method. The tail ginseng, which will be subject to net soil impurities and grading, will be sun-dried for 2-3 days in the sun, and it will be elastic to the sun and will not break easily. Rinse with water before steaming to remove dust. Use a large iron pan (called the lotus leaf pot in the rural area) and boil it with a half pot of water, put a wooden stand in the pot, and put a bamboo sieve on the rack. The bamboo sieve is 0.3-0.4 cm away from the water surface and cannot touch the water surface. Each filter is equipped with 5-7 kilograms of tail ginseng, covered with steam for 8-9 minutes, or out of the steamer can be taken out. At the same time, the next sieve is placed and the water potential is not reduced. According to the classification, the thick stems were steamed first and steamed longer: after steaming thin stems, steaming was shorter. Consider the evaporation of water. After steaming 2-3 sieves, add water. After boiling, steam the sieve. Steamed while turning. Place the steamed tail ginseng on a clean sun pad or door, place it neatly, flip 2-4 times, wait until the yellow, translucent, and then rinse with water. , The next filter will steam well. Rinse a good tail of the Sun under the sun for 4-6 days, rubbing several times, dry sun during the day and night, the accumulation of the night to facilitate resurgence, and then use stove fire or drying room.
Also known as Polygonatum odoratum, rhizomes used as medicine. The root stem is sweet and slightly bitter, has the effect of nourishing yin, moistening dryness and thirst, and is suitable for the treatment of lung and stomach yin injury, dryness and cough, thirst and thirst, internal heat and diabetes.
