The chemical derivatives of morphine made by reacting morphine with acetic anhydride include heroin and acetylcodeine. Heroin is a semi-synthetic opioid with similar effects to morphine but is more potent and addictive. Acetylcodeine is also a semi-synthetic opioid that is used in some countries as a prescription drug for pain relief.
to convert the phthalic anhydride in to phthalimide, it is heated with urea at the temp. of 160 c with out using any solvent. phthalic anhydride + urea = phthalimide +water+ carbondioxide
The chemical equation for the reaction of oxygen reacting with hydrogen to yield water is 2H2 + O2 → 2H2O.
Aniline derivatives, such as p-phenylenediamine, are used in hair coloring due to their ability to provide permanent color results by penetrating the hair shaft and reacting with the natural melanin. These derivatives can produce a wide range of shades, offer good color longevity, and are cost-effective compared to alternative coloring agents. However, they can cause skin irritation and allergic reactions in some individuals.
The balanced chemical equation for magnesium reacting with sulfuric acid is: Mg + H2SO4 -> MgSO4 + H2
Succinic anhydride can be synthesized from succinic acid by reacting succinic acid with acetic anhydride under acidic conditions. The reaction is typically carried out in the presence of a catalyst such as sulfuric acid, which helps in the formation of the anhydride. After the reaction is complete, the succinic anhydride can be isolated by simple extraction and purification techniques.
Daminozide is made by reacting succinic anhydride and1,1-dimethylhydrazine.
Acetanilide can also be synthesized by reacting aniline with acetic anhydride, instead of acetyl chloride. This is known as the Acetic Anhydride Method.
The balanced chemical equation for the reaction between ethylene glycol and phthalic anhydride is: C6H4(CO)2O + 2 C2H6O2 → C6H4(CO2CH2CH2O)2 + 2 H2O From the equation, it can be seen that 2 moles of water are produced for every 1 mole of ethylene glycol reacting with 1 mole of phthalic anhydride.
a paint binder or paint vehicle made by reacting coconut oil with a polyhydric alcohol such as pentaerythritol or glycerol and then reacting the resulting mixture of monoesters with phthalic anhydride
Chemical.

This is a chemical property.
always.
This is a chemical reaction, a chemical change.
Its a chemical change. its like an acid reacting with a base to form salt and water.
The chemical equation for the reaction of oxygen reacting with hydrogen to yield water is 2H2 + O2 → 2H2O.
The chemical equation demonstrates the ratio of chemicals reacting and producing. Even though only minute amount of actual chemicals are reacting, the chemical equation shows which chemicals are doing what.
