Introduction to Industrial Chemistry Quiz

Commodity vs. Specialty Chemicals

• Commodity chemicals are produced in large quantities and have broad applications, while specialty chemicals are produced in smaller quantities and are tailored for specific functions.
• Specialty chemicals often command higher prices due to their unique properties and applications.

Batch vs. Continuous Processes

• Batch processes involve the production of chemicals in discrete quantities with specific start and end times, ideal for varied products.
• Continuous processes involve the ongoing production of chemicals without interruption, maximizing efficiency for consistent product types.

Basic Inorganic Chemicals

• Basic inorganic chemicals include substances like sulfuric acid, known for their foundational role in chemical manufacturing and industry.

Main Use of Sulfuric Acid

• Sulfuric acid is primarily utilized in the production of fertilizers, especially phosphates, and in various industrial chemical processes.

Sulfuric Acid in Polymerization

• Sulfuric acid plays a critical role as a catalyst in polymerization reactions, particularly in the synthesis of polymers from monomers.

Examples of Basic Chemicals

• Ethylene and propylene are categorized as basic chemicals, serving as key building blocks in various chemical industries.

Fine Chemicals vs. Specialty Chemicals

• The primary distinguishing factor is that fine chemicals are produced in smaller, highly pure batches for specific applications, while specialty chemicals focus on functional or performance characteristics.

Unit Processes vs. Unit Operations

• Unit processes involve chemical changes (chemical reactions) to transform raw materials, while unit operations involve physical changes (e.g., mixing, separation) without altering the chemical identity.

Sulphonic Acid Process

• The process of introducing a sulfonic acid group or sulphonyl halide is referred to as sulfonation.

Esterification Outcome

• The main outcome of esterification is the formation of esters through the reaction of alcohols with carboxylic acids.

Hydrogenation Definition

• Hydrogenation refers to the chemical process of adding hydrogen to unsaturated hydrocarbons, often used to convert oils into solid fats.

Nitro Group Addition

• The process that involves the addition of a nitro group (NO2) to organic compounds is called nitration.

Conductivity-Based Separation

• The unit operation that separates solids based on their conductivity is electrostatic separation.

Dissolution Process

• The process of dissolving target solids from unwanted inert solids is known as leaching.

Purpose of Spray Drying

• Spray drying is used to convert liquids into powder form, enhancing the shelf-life, transportability, and usability of the material.

Material Balances Goal

• Material balances in chemical processes aim to ensure that mass is conserved, balancing inputs and outputs in the system.
