Catalyst refers to a substance which can change the reaction speed in a chemical reaction and whose composition and mass remain unchanged after the reaction. The catalysts that speed up the reaction are called Positive Cata-lyst and the slower ones are called Negative Cata LYST or moderators. Generally speaking, the catalyst is to correct the catalyst. These catalysts are widely used in industry, especially in organic chemical industry. They are of great significance, for example, catalysts are needed for the preparation of sulfuric acid by contact method, the hydrolysis of synthetic ammonia, esters and polysaccharides, and the hydrogenation of oils and fats. Commonly used catalysts are metals, metal oxides and inorganic acids. If the catalyst is a solid, the reactant is a gas, forming a heterogeneous catalytic reaction, this catalyst, sometimes called a catalyst or contact agent.
Auxiliaries refer to the industrial and agricultural production, especially chemical production, in order to improve the production process, improve product quality and output, or give the product a unique application performance, usually need to add some auxiliary chemicals. It is a kind of important auxiliary raw materials in chemical production, which can give the products special properties and improve the use of finished products, accelerate the chemical reaction speed and improve the yield of products, save raw materials and improve the processing efficiency. It is widely used in chemical industry, especially in organic synthesis, synthetic material processing and petroleum refining, pesticides, pharmaceuticals, dyes, coatings and other industrial sectors. By use, it can be divided into synthetic auxiliaries and processing auxiliaries. Auxiliaries used in the synthesis and polymerization of resins, fibers, rubber and other monomers are called synthetic auxiliaries, including catalysts, initiators, solvents, dispersants, emulsifiers, polymerization inhibitors, regulators, terminators, etc. Auxiliary chemicals used in the manufacture of rubber, plastic products and in the spinning and spinning of chemical fibers are called processing aids, including plasticizers, heat stabilizers, antioxidants, light stabilizers, flame retardants, foaming agents, lubricants, demoulding agents, vulcanizing agents, accelerators, softeners, anti-scorching agents. Agents, surfactants, oils, fillers and so on. Many of these Additives are dangerous chemicals, such as diphenyl peroxide, azodiisobutyronitrile, hydrogen peroxide-ferrous blue, alkyl aluminum, titanium chloride and other initiators, catalysts are inflammable and explosive materials, should be stored and transported in accordance with the relevant provisions of the Regulations on the Safety Management of Chemical Hazardous Goods. Management and use.

The huge pink sepals and drooping spikes resemble fairy lights that fall from heaven to the earth. This novel and exotic flower is the Po Lotus. It is also known as the gemstone lotus lamp, vine vine, and its scientific name is powdered oleoresinate. It is a perennial evergreen shrub of the genus Myrobalaceae and acid pedicel. The normal plant height of Baolianhua is about 2.5 meters, but it is mainly planted in China and the plant height does not exceed 70 centimeters. Its stems are quadrangular or quadrangular, branching flat, single leaves opposite, sessile. Leaves ovate or oblong, shiny leathery, veins base. The spikes droop, the corolla diameter is about 2.5 centimeters, red or pink, the flower outer leaf length is 3 centimeters to 10 centimeters, is bright pink, the greenhouse flowering period is from April to May, each flower can open 2 Around the week. After flowering, it bears a pink berry, spherical, with persistent sepals at the top. Born in tropical rainforests in tropical Africa and Southeast Asia, Baolianhua has a warm and humid environment. Its optimum temperature for growth is 18°C ​​to 22°C. It is not tolerant to cold and it has a bright and pleasing environment. It is slightly shade-tolerant and avoids exposure. Drought tolerance requires loose soil and good drainage. Po Lotus has high requirements for cultivation and conservation. Spring and autumn are the peak seasons for growth. Especially after the flower buds are extracted in April, they need to be watered more often and sprayed on the foliage to keep the basin soil moist and high humidity. Before and after flowering, topdressing should be carried out. The organic fertilizer and compound fertilizer should be used alternately for 10 days to 15 days. After flowering, the peduncle should be cut off from the base. After entering the summer, fertilization should be stopped, shading and ventilation, and water spray cooling. In winter, when the plants enter into dormancy, the amount of watering should be gradually reduced, and the pots and soils should be kept dry. Give plenty of light and keep the room temperature above 10°C. The breeding of Baolianhua is mainly based on cuttings. When the vase is changed after flowering, the tip of the plant is cut off and the lower leaves are removed. After treatment with the rooting agent, the earthworm is inserted into the meteorites, the cover film is moistened, and the moonlight can be used at 20°C. root. The lotus flower, leaves and fruit are all beautiful, especially the flower shape is ten, and the potted hanging in the living room has high ornamental value.
