Thirty alkyl alcohol toxicity data

More than thirty alkanol exist in a variety of plants and insects in the form of an ester waxes. No toxic effects were found on the human and animal and the beneficial organisms.

Thirty alkyl alcohol physical and chemical properties

Appearance is white scale crystal, melting range of 85.5-86.5 degrees Celsius, insoluble in water, difficult to dissolve in cold methanol, ethanol, acetone, soluble in ether, chloroform, carbon tetrachloride. Product performance is stable, can be stored at room temperature for a long time.

Thirty alkyl alcohol development process

Thirty alkanol is a natural long carbon chain of plant growth regulators, the chemical name is thirty alkanol, structure type CH3 (CH2) 28CH2OH, also known as melissyl alcohol, is the purification of natural biological products extracted from bee wax. Harmless to people and animals and side effects, no pollution to the environment. A developed agricultural country, in early twentieth Century seven, 80s has been fully spraying thirty alkanol, as agricultural harvest yield, optimize the quality structure of plant growth regulators in China, because the technology is not perfect, no rigorous attitude, full of mistakes act with undue haste. Thirty alkanol is to develop the national Spark plan, completed in 96 years. Rejuvenated thirty alkanol and world level synchronization, and it will become "WTO" accompanied by the reform of agricultural structure, optimize the product and maintain ecological balance, return to nature, improve the yield, provide technical material for green food.

Thirty alkyl alcohol effect characteristics

1, thirty alcohol can be absorbed through the stem and leaf of the plant, and promote plant growth, increase the accumulation of dry matter and improve the cell membrane permeability and increase the chlorophyll content, photosynthetic rate, amylase, oxidase, peroxidase activity.

2, thirty alkyl alcohol can promote germination, rooting, stem and leaf growth and flowering, so that crop maturity, improve seed set rate, enhance the cold resistance, drought resistance, increase production, improve product quality.

3, foliar spraying, the general use of the concentration of 0.5ppm.

Thirty alkyl alcohol synthesis method

30% up to thirty alcohol content of 1 Chinese beeswax in general consists of thirty palmitic acid alkyl ester and wax acid alkyl ester thirty and sixteen acid alkyl ester thirty. These esters react with the base to produce a high level of fatty acid sodium and thirty alkyl alcohols. After the addition of solvents (such as benzene, petroleum ether, etc.), and then take off the solution can be obtained with thirty alkyl alcohols and other higher alcohols and hydrocarbons of the product, and then after the removal of hydrocarbon purification and get pure product thirty alkyl alcohol. Total yield 15% ~ 10%. Sometimes, when added in the saponification of phase transfer catalyst (quaternary ammonium salt or ether), can shorten the reaction time, thirty alcohols yield also increased slightly.

2 the wax melting and filtering to remove mechanical impurities, clean the transparent yellow beeswax. Then clean the beeswax and industrial alcohol heating to boil, pour out the alcohol solution, repeated 2 times with alcohol extraction, liquid cooling, filtering, light yellow solid, and hot alcohol insoluble combination. The prepared solid sodium hydroxide solution and benzene and ethanol refluxing, saponification, then add water, stirring and washing, to remove water, benzene, light yellow viscous crude. In the end, the white crystalline product of thirty alkyl alcohols was prepared by the mixed solvent recrystallization.

Thirty alkyl alcohol use method

1 rice 0.5-1mg/kg 2 days after sowing seed germination liquid. Can improve the germination rate, increase the germination potential, increase production 5%-10%.

2 soybean, corn, wheat and millet with 1mg/kg liquor soaking 0.5-1 days after sowing, can improve germination, germination potential, enhance the yield by 5%-10%.

3 leafy vegetables, potato, sugarcane seedlings, grass, etc. with 0.5-1mg/kg liquid spraying stems and leaves, yield more than 10%.

4 fruit trees, Solanaceous Vegetables, cereal crops, soybean and cotton with 0.5mg/kg liquor in flowering stage and full bloom stage of the spray 1 times also increase yield.

5 cuttings seedlings with 4-5mg/kg soaking liquid, can promote rooting.

6 kelp soaking liquid with 0.5-1mg/kg about 14cm long soaking liquid is about 14cm long kelp 6h, can increase more than 20%, and the kelp leaf length, width and thickness of growth accelerated, with dry matter increased 7%, alginate and mannitol increased obviously.
