Why do we need solvents
Answered By: Graham Jackson Date: created: Mar 06 2021
The term ‘solvent’ is applied to a large number of chemical substances which are used to dissolve or dilute other substances or materials.
They are usually organic liquids.
Many solvents are also used as chemical intermediates, fuels, and as components of a wide range of products..

What is a neat reaction
Answered By: Howard Harris Date: created: Nov 19 2021
‘Neat’ loosely means pure. If you run a reaction neat, you are only dealing with the reactants – no solvent or catalysts/initiators. One of the reactants could be solvent or it could be a solid-state or gas/plasma-phase reaction. Often, chemicals like acetic acid or hydrogen peroxide will be watered down.

What makes a good solvent
Answered By: Angel Ramirez Date: created: Jun 19 2021
Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the “universal solvent” because it dissolves more substances than any other liquid. … This allows the water molecule to become attracted to many other different types of molecules.

Answered By: Jeremiah Watson Date: created: Jan 22 2022
Solids do not react with solids at room temperature even of thermodynamics is favorable. High temperature must be used. Solid-solid reactions are simple to perform, starting materials are often readily available at low cost and reactions are “clean” i.e. do not involve other chemical elements.

What does it mean solvent free
Answered By: Alfred Powell Date: created: Mar 25 2021
Solvent-free refers to a substance that contains little or no solvent. Paint, adhesives, hash oil and epoxy are substances that normally contain very little solvent. … Solvent-free epoxy resin is solid and contains no water or solvent as diluents. Solvent-free indicates that the substances are environmentally friendly.

Whats the difference between solvent and solvent free
Answered By: Austin Lee Date: created: Dec 29 2021
The main difference between the two is that solvents free is water based and contains less than 5% of solvents, whereas the the solvent based contains a much larger amount. This makes them safer and more comfortable to use in small spaces like bathrooms, due to the low odour/odourless attributes of the adhesive.
