Process for the manufacture of a dialkylphenylethylmalonatewhich comprises adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C, at least a chemically equivalent proportion of methyl, ethyl or a propyl alcohol, subsequently adding an approximately equivalent proportion of a dialkylcarbonate and of an alkyl phenylacetate, the alkyl groups in these two last-mentioned compounds being preferably the same as the alkyl radical of the above –mentioned lower aliphatic alcohol, heating the mixture to induce reaction and continually distilling out the alcohol formed from the reaction zone and finally causing the sodio diethyl phenylmalonate so formed to interact with an ethylating agent.

The results are the following: When calculating the motion mass, it is better to use idler's equivalent mass instead of the rotating part mass and serial idler's rotating inertias and equivalent mass are calculated. The accurate analysis result for the deflection curve length of the belt shows: The error calculated by the approximate parabola length is lower than 10〓. Thus the approximate method is accurate enough for calculation. The relations between the running resistances coefficient and the belt velocity are studied by experiment, which are the bases for calculating the linear coefficient values between them.
