有机物燃烧的计算是有机化学的重要内容，它广 泛应用于有机物耗氧量的比较、分子式的确定等许多 方面，本文就其中的规律及其应用作一些总结。 一、有机物耗氧量的比较： 1、烃(C_xH_Y)的耗氧量： 规律1、由烃的燃烧通式可知，物质的量一定时， 烃的耗氧量决定于(X+Y/4)的大小，其值越大，烃的 耗氧量就越大。
The calculation of the combustion of organic matter is an important part of organic chemistry. It is widely used in many aspects such as the comparison of oxygen consumption of organic matter and the determination of molecular formulas. This article summarizes the laws and applications of organic matter. I. Comparison of oxygen consumption of organic matter: 1. Oxygen consumption of hydrocarbons (C_xH_Y): Law 1. It can be known from the general formula of hydrocarbon combustion that when the amount of material is fixed, the oxygen consumption of hydrocarbons is determined by (X+Y/4). The larger the size, the greater the oxygen consumption of the hydrocarbons.
