Methoxychlor is produced by condensing anisole and trichloroacetaldehyde in the presence of fuming sulfuric acid or aluminum trichloride.

Purpose

1. An organochlorine pesticide. This product is a non-systemic contact and stomach poisoning insecticide with slight aphidicide or acaricidal activity. Its biological activity range is roughly the same as that of DDT. Because it has little or no tendency to accumulate in body fat or be secreted into milk, it is recommended for fly control in dairies and dairy cows. This product can also be used to prevent and control household sanitary pests, animal ectoparasites, vegetable and fruit tree pests, replacing DDT. The maximum allowable residual amount is: 2 mg/kg for grain, 14 mg/kg for fruit trees, and 100 mg/kg for feed. The ban period before harvest is 7 to 21 days. For example, when using 25% EC to control poplar loopers and aphid weevils in poplar and jujube trees, spray at 625 to 1250 mg/L.

2.Organochlorine pesticides. It has contact and stomach poisoning effects, no systemic effect, wide insecticidal spectrum, low toxicity to humans and animals, no cumulative effect in the organism, and is easily decomposed by multifunctional oxidase and converted into water-soluble non-toxic excreta. It can be used for field crops, fruit trees, vegetables and other crops to control corn borers, bridge-building insects, bean beetles, pea weevils, fruit tree borers, codling moths, Japanese beetles, small weevils, canopy caterpillars, and fruitFlies, leafhoppers, stink bugs, vegetable leaf flea beetles, diamondback moths, cucumbers, seed flies and other pests. It can also be used to control ectoparasites and sanitary pests in livestock.

Properties and stability

1. Stable under normal temperature and pressure.

2. Exist in flue-cured tobacco leaves, burley tobacco leaves and smoke.

Storage method

Tightly packaged in brown wide-mouth glass bottles. Store in a cool, dry place away from light.

Synthesis method

1. It is produced by fermenting sugar, ammonia and homoserine with glutamic acid-producing Pediococcus, Brevibacterium, Corynebacterium, etc., and then refining it. The concentration in the fermentation broth can reach 5-20g/L.

2.Prepared from crotonic acid or glycine as raw material. Glucose or starch can also be used as raw materials, and the product can be obtained through fermentation and refining using Escherichia coli, Brevibacterium flavum, Bacillus glutamicum or Corynebacterium craniodonta as strains.

3.L-The industrial production methods of threonine mainly include: ① synthesis method; ② fermentation method; ③ protein hydrolysis method Three types. Fermentation production is now advocated.
The fermentation method uses sugar, ammonia, and homoserine (homoserine) as the culture medium, and is fermented with glutamic acid-producing Pediococcus (glutaminus) and refined to produce L-threonine.

4.Extraction method

5.The injection preparation method is as follows

6. Tobacco: BU, 22; FC, 21; Synthesis: It can be obtained by hydrolysis and purification of proteins (such as casein), or synthesized from methanol and mercury acetate in acrylic acid derivatives.

Purpose

1. Mainly used as nutritional supplement. When heated with glucose, it easily generates caramel and chocolate aromas, and has a flavor-enhancing effect. Can also be used for biochemical research.

2.As a feed nutritional fortifier, threonine is an essential amino acid. Threonine is often added to the feed of immature piglets and poultry, and is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed. Added to feeds based on wheat, barley and other grains.

3.Nutritional additives, also used to prepare amino acid infusions and comprehensive amino acid preparations.

4.For the auxiliary treatment of peptic ulcer. It can also treat anemia and cardiovascular system diseases such as angina pectoris, aortitis, and cardiac insufficiency.
