一、题型特点化学工艺流程题往往与生产、生活实际密切联系,试题源于生产实际,以化工生产背景,内容呈现探究性、应用与创新性的特点,从题干部分看一般都是采取流程图的模式,流程图的形式各异,有的以操作名称作为框图形成流程的主线,或以物质作框,或以设备作框,但每一题都固定以上一种形式为框,以操作名称为主线、物质随着操作发生变化的形式较为多见,此类题中通常还包含简单的实验设计,且实验一般为制备或对样
First, the characteristics of the type of chemical process flow problems are often closely linked with the actual production, life, the test from the actual production to chemical production background, the content of inquiry, application and innovative features, from the dry part of the general are taken Flow chart patterns, flow charts in various forms, some with the name of the operation as a block diagram form the main line of the process, or material for the box, or equipment for the box, but each question is fixed in the above form as a box to The name of the operation as the main line, the material changes with the operation of the form is more common, such questions usually contain simple experimental design, and the experiment is generally prepared or sample
