Product Storage:

in dry warehouse ventilation should be more than 10mm from the ground to avoid damp  products in the above-mentioned conditions, from the date of delivery for one year shelf life.


Q: What is organic matter?
Organic compounds (organic compounds) mainly by the oxygen elements, hydrogen, carbon elements. Organic matter is the material basis for life. Fat, amino acids, protein, sugar, heme, chlorophyll, enzymes, hormones and so on. Biological metabolism and biological genetic phenomena, are related to the transformation of organic compounds. In addition, many substances closely related to human life, such as oil, natural gas, cotton, dyes, chemical fiber, natural and synthetic drugs, are organic compounds.
Q: Organic organic compounds are organic matter?
The polymer compound is covalently bonded to each other by thousands of atoms to form a compound having a relatively large molecular mass and having a repeating structural unit. But the number of repeating units in the preparation process is often not the same, so that the organic polymer compound is a mixture of the argument is not wrong, of course it is organic matter which is beyond doubt.
Q: What is the relationship between hydrocarbon and hydrocarbon derivatives?
Hydrocarbons, which are composed of two elements, carbon and hydrogen, are called hydrocarbons and hydrocarbons. It reacts with chlorine, bromine vapor, oxygen, etc. to produce hydrocarbons.
Q: Are all carbon compounds all organic?
Not organic matter that is organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.
Q: Is not organic matter must not hydrogen ah?
Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate
Q: Peracetic acid is not
A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered
Q: Is fatty acid and carboxylic acid the same thing?
In contrast, aromatic acids refer to carboxylic acids with benzene rings
Q: High school chemistry: Is the esterification reaction of carboxylic acid and alcohol a polymerization reaction?
No, the polymerization reaction is the reaction of the polymer, the esterification reaction is the reaction of the formation of small molecules
Q: What are the characteristics of the reduction of carboxylic acid and its derivatives?
NaBH4-ZrCl4 reagent system In the THF-toluene mixed solvent, at the reflux temperature, some of the carboxylic acid and its derivatives can be reduced to obtain the corresponding high yield of alcohol.
Q: The nature and use of cellulose derivatives
The basic rules of esterification and etherification of cellulose In the cellulose molecule, the position of the three hydroxyl groups in the glucose group is different, and the influence of the adjacent substituents and the spatial blocking effect are different. The relative acidity and dissociation of the three hydroxyl groups are: C> C> C When the etherification reaction is carried out in the alkaline medium, the C hydroxyl group first reacts, then the C hydroxyl group, and finally the C primary hydroxyl group. In the acidic medium for esterification reaction, the reaction of the hydroxyl reaction is difficult and etherification reaction in the opposite order. When reacted with a larger amount of substituted reagents, the spatial hindrance has an important effect, and the space hindering the smaller C hydroxyl groups is easier to react than C and C hydroxyl groups.
