Stearic Acid 1668

Q: Does the carboxylic acid react with the Grignard reagent?: Reaction. Grignard reagent is an organic strong base, first and the acid reaction of carboxylic acid to produce magnesium salt, and sometimes further nucleophilic attack, control conditions will get different products, but the first acid-base reaction is unavoidable.

Q: What is the derivative of benzene?: Benzene homologues: the structure of similar molecular composition of a number of different groups of CH2 atoms.

Q: The main role of sugar?: The energy of life

Q: Which acid is strong for carboxylic acid and carbonic acid?: carboxylic acid

Q: Cracked: It is almost impossible for this problem to look at your reaction conditions. Generally speaking, the alkane reaction is mainly difficult to decompose directly into ions

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

Q: Carboxylic acid in the end can not react with the new copper hydroxide: But the formula is written in the carboxylic acid, because the reaction of aldehydes with the new copper hydroxide is alkaline conditions, the carboxylic acid is not present, but the carboxylic acid and alkali, copper hydroxide, copper oxide are reaction, Side reactions too much, too complex, in order to show that the reaction principle, simply from the simple processing, directly write carboxylic acid

Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: Agree upstairs chemdraw method.

Q: The nature and use of cellulose derivatives: By replacing the reagent selection and process design, the product can be dissolved in water, dilute alkali solution or organic solvent, or have thermoplastic properties such as chemical fiber, film, film, plastic, insulating material, coating, slurry , Polymeric dispersants, food additives and household chemical products. The nature of the cellulose derivative and the nature of the substituent, the degree of substitution of the three hydroxyl groups on the glucose group, and the distribution of the substituents along the macromolecular chain. Due to the randomness of the reaction, the following three substitutions are different in other cases (homogeneous or heterogeneous reactions) except that the three hydroxyl groups are substituted (DS = 3) And non-substituted glucose groups: (1) monosubstituted (DS is 1, C, C or C position is substituted, the structural formula see cellulose); ② disubstituted (DS is 2, C, C, C, C Or C, C position is replaced); ③ total substitution (DS is 3). Thus, the properties of the same cellulose derivative having the same substitution value may also be quite different. For example, the cellulose diacetate which is directly esterified to DS of 2 is insoluble in acetone, but the cellulose diacetate obtained by saponification of the fully esterified cellulose triacetate can be completely dissolved in acetone. The irreducibility of this substitution is related to the basic rule of cellulose ester and etherification.
