Q:What is a derivative?: Derivative refers to a simple compound in the hydrogen atoms or atomic groups replaced by other atoms or atomic groups derived more complex products

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.

Q:Derivatives of vinyl acetate: Vinyl acetate can produce reactions that occur most of the olefins or esters. Such as the addition of bromine to form dibromide, the addition of hydrogen halide to produce vinyl haloacetate, which is the only way to produce the substance because there is no corresponding halohydrin. The addition of acetic acid under palladium catalysis can produce ethylene diacetate and CH3CH (OAc) 2. The latter can undergo a transesterification reaction with many carboxylic acids. As an alkene, vinyl acetate can also undergo a Diels-Alder reaction and a 2 + 2 ring addition
