Properties of urea
Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 â?? under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present.
Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm �³ï¼? The melting point is 132.7 â??. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 â?? and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 â??ï½? 160 â?? to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 â??, and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption.
Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces.
The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made.
New standard GB/T2440-2017
Description: Sodium erythorbate is a white or yellow white crystalline powder or granules, odorless, has little salt, the melting point is over 200, it is rather stable when being dry exposed to the air, but in the water solution, when there is air, metal, heat and light, the oxidation will occur. It easily dissolves in water; 16g/100ml at normal temperature, hardly dissolves in ethanol, the PH value of 2% water solution is 5.5-8.0.
Which complies with the specifications of GB8273-87, FCC for food additives
Net Weight: 25kgs/carton.
Uses: Sodium Erythorbate is mainly used in foodstuff industry, used as antioxidant, preservative and coloring agent, broadly used in meat food, fish food, beer, fruit juice, syrup crystal, fruit and vegetable tin, cake, dairy produce, confiture, sherry, pickles, and grease etc. the dosage to the meat foods is 0.5~1.0g/kg. To the frozen fish, the fish should be infused in the 0.1%-0.8% water solution before freezing. The dosage in the beverage such as syrup is 0.01%~0.03%, apple and bechamel tin: 0.15g/kg (dosage of single or together with the VC), luncheon meat, cooked meat powder, cooked front leg pork, cooked ham, the dosage is 0.5g/kg (dosage of single or together with the VC and other sodium salt, counted the VC ), for the peach, apple jam: 2g/kg,for the fruit tin, it is 0.75-1.5g/l, for the nature syrup, it is 0.08-0.11g/l, for the beer, it is 0.03g/l (FAO/WHO(1977).
Antioxidation property: the antioxidation property of the Sodium Erythorbate is great larger than the one of cenolate (Sodium VC), has no effects to identify the Vitamin C, but it will not persuade the body to absorb and use the Sodium Erythorbate. The body culls the Sodium Erythorbate and changes it into Vitamin C inside the body.
The physiological effects of the Sodium Erythorbate is only the 1/20 of the VC on anti-scurvy, but it is approximately same to the VC on drop blood pressure, diuresis, generating of hepatic glycogen, discharging of pigment, detoxifcation.

Animal husbandry can be used as feed for ruminants. However, excessively high temperature in granulation will produce a small amount of biuret, also known as biuret, which has an inhibitory effect on crops.
my country stipulates that the content of urea biuret used in fertilizers should be less than 0.5%. When the biuret content exceeds 1%, seed fertilizer, seedling fertilizer and foliar fertilizer cannot be used, and the urea content in other application periods should not be too much or too concentrated.
Urea is an organic nitrogen fertilizer. After being hydrolyzed into ammonium carbonate or ammonium bicarbonate by the action of urease in the soil, it can be absorbed and utilized by crops. Therefore, urea should be applied 4 to 8 days before the fertilization period of the crop.

Cobalt oxide (Co203) is an expensive cobalt oxide with a theoretical cobalt content of 71.06%, an oxygen content of 28.94%, and a density of 6.079/cm3. It is a black amorphous powder that generates cobalt oxide (Co304) after heating. Cobalt oxide is an unstable compound and cannot be freed. The cobalt oxide commonly referred to actually still contains a certain amount of cobalt tetraoxide. Co203 is only stable in a hydrated state. This hydrate will dehydrate and transform into the intermediate oxide cobalt tetraoxide (Co304) at 265�°C. Cobalt oxide is reduced to cobalt tetraoxide (Co304) by H2 at 125�°C, reduced to CoO at 200�°C, and reduced to cobalt metal at 250�°C. Cobalt oxide is insoluble in water. After dissolving in water, it decomposes into hydrates when it encounters water. It is insoluble in water, but soluble in acid and forms corresponding salts.
