摘要

是什么让塑料材料如此受欢迎?什么环境问题正在出现,正在征服整个世界?今天,我们可以看到我们周围的一切都是由塑料制成的。我们大多数人都知道我们周围的大多数东西都含有塑料。然而,尽管应用范围很广,但也出现了许多问题。常见的例子包括塑料污染、塑料净化过程,以及向垃圾中排放污染环境的气体及其物质。肆意焚烧塑料导致致命气体和致癌物排放到环境中。将它们倾倒在垃圾填埋场导致毒素浸出到地下和地表水资源中。最近,随着塑料回收,我们正在考虑生产生物塑料的方法,可以代替塑料,分解需要几百年。由于它们的天然来源,它们比普通塑料更容易生物降解。本工作的目的是研究生物塑料的制备方法,并在实验室中制备生物塑料。作为这项工作的结果,在实验室中获得了生物塑料团块,并对所得产品进行了水解。水解在三种不同的环境下进行。这是因为环境的pH值可以不同。由于同样的原因,在弱酸、弱碱和中性环境下都进行了反应。通过观察水解结果,确定了产物的变化。然而,为了解释其在分子背景下的变化,使用了红外光谱的方法,并对结果进行了讨论。

Study of the possibility of obtaining bioplastic
What makes plastic materials so popular? And what environmental problems are emerging, conquering the whole world? Today, we can see that everything around us is made of plastic. Most of us know that most of the things around us contain plastic. Despite the wide range of applications, however, there arise many problems. Common examples include plastic pollution, plastic decontamination processes, as well as the release of gases and substances thereof into the garbage, which pollute the environment. The indiscriminate burning of plastic results in the emission of deadly gases and carcinogens into the environment. Dumping them in the landfills results in leaching of toxins into the ground and surface water resources. Recently, along with plastic recycling, we are considering ways to produce bioplastics that can replace plastics, to decompose which it takes several hundred years. Due to their natural origin, these are more biodegradable than ordinary plastic. The purpose of this work is to study the ways of obtaining bioplastics, and obtaining bioplastics in the laboratory. As a result of the work, bioplastic mass has been obtained in the laboratory, and hydrolysis of the resulting product has been carried out. Hydrolysis has been performed in three different environments. This is because pH of the environment can be different. For the same reason, it has been carried out in a weak acid, a weak base environment and a neutral environment. By observing the hydrolysis results, the resulting product changes have been determined. However, to explain its change in the context of the molecule, the method of infrared spectroscopy has been used, and results have been discussed.
