Description

Name of Notes : – Heavy and Fine Chemicals (Chemical Process Technology) Lecture Note

Introduction

Overview

Chemical industries are basically divided into two groups.
First which produces simple compounds from the locally available large amount of raw materials usually they are very large industries and the product manufacture are purified to the extent that they can be used as raw material for other industries or they are directly marketed as a consumer goods. In general they are heavy chemical industries.
On the other hand certain industries deal with specialty chemicals and they are making small quantity of product having better quality which is sold into market as finished good. They are called as fine chemical industries.

Classification

The materials used or produced in the chemical industries are classified in the following manner.
1. Quantity of production and consumption
a) Heavy chemicals
Those dealt in large quantity normally crude or less purified chemicals.
E.g. mineral acid, NaOH, Na2CO3 etc.
b) Fine chemicals
They are complete purified substances and produced in limited quantity.
E.g. specialty solvent, perfumes, medicines etc.
2. Chemical composition
a) Organic compound
Compounds having carbon atom in the main structure of the molecule is called organic compound.
E.g. hydrocarbons, phenols, carboxylic acid etc.
