The velocities of reaction of ethyl acetate with sodium hydroxide in dioxane- water mixture have been determined in seven different temperatures(5°,10°, 15°,20°,25°,30°and 35°).For each temperature,the compositions of solvent mixture are 0,5,10,15,20,25 and 30% of dioxane.We thus obtain 49 velo- city constants as summarized in the following table.

The velocities of reaction of ethyl acetate with sodium hydroxide in dioxane- water mixture have been determined in seven different temperatures(5°,10°, 15°,20°,25°,30°and 35°).For each temperature,the compositions of solvent mixture are 0,5,10,15,20,25 and 30% of dioxane.We thus obtain 49 velo- city constants as summarized in the following table. At low temperatures,the velocity constant decreases slightly with decrease of dielectric constant of solvent.At higher temperatures,such decreases of k' become more pronounced. The“isocomposition”energy of activation decreases slightly with increase of percentage of dioxane in the solvent mixture. The“isodielectric”energy of activation shows practically no change,when the dielectric constant changes from 80 to 50.Its value is 11300 calories. The experimental data are compared with the three modern theories of ion- molecule reaction,namely,by(1)Moelwyn-Hughes,(2)Laidler and Eyring and (3)Amis and Jaffe.From the viewpoint of influence of dielectric constant on the rate of the present reaction,the first two theories disagree qualitatively with our experimental data,while the last one,though qualitatively successful,fails quantitatively.(The “enhanced moment” and index of refraction as calculated from the last theory with the use of our data are unreasonably large.)

作者在7具不同温度(5°,10°,15°,20°,25°,30°,35°)下,研究了乙酸乙酯和氢氧化钠在二氧六圜和水的混合溶剂中的反应速度。每个温度有7个不同的二氧六圜和水的成分(0%,5%,10%,15%,20%,25%,30%的二氧六圜),因此得到49个速度常数。在每个温度里,反应速度常数随溶剂介电常数的减小而略为下降:温度愈高,下降趋势愈为显著。同溶剂成分的活化能随着溶剂里二氧六圜成分的增加而略为下降。同介电常数的活化能,在80至50的介电常数范围中,却和介电常数的变化无关。它的平均值是11300卡。我们用实验结果检验最近三个溶液里离子和分子反应速度理论:(1)Moelwyn-Hughes 的、(2)Laidler-Eyring 的和(3)Amis-Jaffe 的理论。就介电常数对反应速度的影响来说,理论(1)和(2)在质上就不和实验相符。理论(3)在质上似和实验相符,但在量上却相差太远。因此就乙酸乙酯对氢氧化钠的反应来说,三个理论都是不合的。

Methylchlorosilanes were successfully chlorinated with sulfuryl chloride, when azo-bis-isobuty-ronitrile was used as free radical initiator, giving the corresponding monochlorinated products. The rate of reaction decreased when more Si-Cl bonds were present in the silane to be chlorinated. Increasing the quantity of the initiator increased the rate of reaction.Trimethylchloromethylsilane was also chlorinated with sulfuryl chloride and benzoyl peroxide, both dichloromethyltrimethylsilane and di(chloromethyl)dimethylsilane...

A more general mathematical analysis of the kinetics of polycondensation-depolycondensation reactions is given in the article. Three different types of reactions are considered, namely, (1) reactions between molecules AB and AB, (2) reactions between molecules AA and BB, (3) reactions between molecules AA and BC. One of the condensation products is assumed (without loss of generality) to be water.For reactions of the first type, [p_n], the number of molecules of the n-mer (AB)_n, obeys the following Flory distribution: [p_n]=N_0p~(n-1)(1-p)~2 where N_0 denotes the total number of AB segments (including the unreacted monomers). and p, as defined by is a measure of the degree of condensation. It is shown that p is the solution of the following differential equation: dp/dt=k/2N_0(1-p)~2-k_(-1)p[H_2O] where K and k_(-1) are velocity constants of condensation and hydrolysis respectively, and [H_2O] denotes the number of water molecules. Three special cases are discussed.For reactions of the second type, three different types of condensation products are possible besides water; they obey the following distributions: [p_(2n)]=2N′_0r~(n-1)p~(2n-1)(1-p)(1-rp) [p′_(2n-1)]=N′_0r~(n-1)p~(2n-2)(1-p)~2 [p″_(2n-1)]=N′_0r~(n-2)p~(2n-2)(1-rp)~2 where N′_0 and N″_0 denote the total number of segments AA and BB respectively, r denotes the ratio N′_0/N″_0, and p, as defined by is the solution of the following differential equation: dp/dt=kn′_0/r(1-p)(1-rp)-k_(-1)P[H_2O]For reactions of the third type, six different types of condensation products are possible besides water; they obey the following distributions: [P′_(2n)]=NP~(n-1)q~n(1-p/2-q/2)(1-p) [p″_(2n)]=Np~nq~(n-1)(1-p/2-q/2_(?))(1-q) [p_(2n-1)=Np~(n-1)q~(n-1)(1-p/2-q/2)~2 [p′_(2n-1)]=N/4p~(n-2)q~n(1-p)~2 [p″_(2n-1)]=N/4p~nq~(n-2)(1-p)~2 [p′″_(2n-n)]=∈(n)N/4p~(n-1)q~(n-1)(1-p)(1-q),where N denotes either the total number of segments AA or that of BC, while p and q, as defined by satisfy the following set of differential equations: dp/dt=k′N/2(1-p)(2-p-q)-k′_(-1)p[H_O] dq/dt=k″N/2(1-q)(2-p-q)-k″_(-1)q[H_2O]

本文討論AB型,AA和BB型以及AA和BC型分子间的缩聚-裂解反應,由動力学方程出發,得到这三种类型反應过程中高聚分子的分佈情况,并求得几种不同反應條件下的缩聚度p和q是何种時间的函数,利用它们和实验数值比較,可以求得縮聚反應速度常数K和水解反應速度常数k_(-1),并在AA和BC型分子间的反應中,可以求得K'和K″的此值,藉以比较官能團B和C的活潑度。还討論了三种平均分子量的表示式、数值以及它们相互的比值,後者僅在没有水解作用的情况下,才和Flory的结果相同。
