Stearic Acid Powder

Q: What is organic matter?: Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q: What is cigarization?: The so-called eggplant, cigar egg alcohol cycle strict sense of each different cigars will have a slight difference, but generally still follow a certain law. There is an economic cycle concept in economics that can be applied to the alcoholic mature cycle of cigar applications. Each cigar has a certain maturity cycle, after the peak after the quality will decline with the taste and decline. The more cigars are, the greater the impact of alcoholic time on them. For example, for three months, the impact on fresh cigars can be huge, but for five years or more the impact of cigarettes is minimal.

Q: Sodium can be used to identify derivatives of hydrocarbons: The alcohol reacts with sodium. (Such as phenolic C6H5OH, cresol CH3C6H4OH, etc.), carboxylic acids (such as formic acid HCOOH, acetic acid CH3COOH, etc.) (description: hydroxyl groups in the carboxylic acid are hydroxyl groups in the carboxyl group) and hydroxyl groups containing polyhydroxyaldehydes and polyhydroxy ketones Such as glucose, fructose, etc.)

Q: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?: No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.

Q: Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?: What is the total hydrocarbon for non-methane? Non-methane total hydrocarbons generally refer to all volatile hydrocarbons other than methane (which are predominantly C2 to C8), abbreviated NMHC

Q: Calcium fatty acid is an organic or inorganic chemical: All fatty acids are organic chemicals

Q: Carboxylic acid and carboxylic acid: The carboxylic acid can not react with the carboxylic acid, which is esterified with a hydroxyl alcohol, for example, acetic acid (acetic acid) reacts with ethanol (alcohol) to produce ethyl acetate with a special flavor.

Q: Inorganic chemistry employment direction? Current research direction: Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.

Q: Benzene derivatives are named from small groups to large groups or from large to small. The following three examples contradict each other ah!: The first should be called p-ethyl toluene, 2,3 pairs, should start from small groups.

Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Artemisinin is relatively stable, is relative to other organic peroxide in terms of, in general, most of the organic peroxide instability, heating easily decomposed, and some even easy to burn the explosion, such as dibenzoyl peroxide, but crystal cyan Artemisinin heating to the melting point does not break down, has been considered stable.
