Science and Technology 110 Science and Technology Co., Ltd. QQ Group User “Guo’an Liu Yong†Q: This year's corn, every 20 or 30 meters, there is a non-pollinated, ear without kernels, this is not the case for adjacent land types. what happened?
Science and Technology 110 experts: This phenomenon belongs to the abnormality of empty corn or ear, which is related to the continuous high temperature and drought weather this year. It is also related to the growth period of the variety and its tolerance and planting density. If maize consistently encounters persistent high-temperature droughts above 35°C during the spike differentiation period after jointing, it may cause damage to the flower formation of the corn and eventually affect the formation of the ear, leading to empty trees or empty ears.

Sodium Methoxide Application
1. Mainly used as raw materials for medicines and pesticides, also used in dyes and chemical fiber industries.
2. It is used as a condensing agent in organic synthesis, as a catalyst in the treatment of edible oils and fats, and as an important raw material for the synthesis of drugs such as sulfamididine, sulfamethoxazole and sulfonamide synergist.
3. Used as an alkaline condensing agent and catalyst in organic synthesis, used in the synthesis of perfumes, dyes, etc., and is a raw material for vitamins B1, A and sulfadiazine.
4. Used as a condensing agent for organic synthesis
5. Fat transesterification catalyst. To change the fat structure, make it suitable for margarine and so on. Must be removed in the final food.
6, mainly used as a condensing agent, strong alkaline catalyst and methoxylation agent, used to prepare vitamin B1 and A, sulfadiazine and other drugs, a small amount for pesticide production. It is also used as a catalyst for the treatment of edible fats and edible oils, especially lard. Also used as an analytical reagent.
