Procaine and procaine monohydrochloride (Novocain) can be prepared from amino benzoic acid in two ways. The first way directly reacts 4-aminobenzoic acid ethyl ester with 2-diethylaminoethanol in sodium ethoxide. The second way reacts 4-nitrobenzoic acid with thionyl chloride. The resulting acid chloride is esterified with 2-diethylaminoethanol. Then the nitro group is reduced by hydrogenation over nickel catalyst.

Extensive or intensive?
Neither. Benzoic acid is... benzoic acid. Intensive and extensive are properties are characteristics of elements and compounds such as color, density, odor, conductivity, etc. To say benzoic acid is extensive or benzoic acid is intensive doesn't make sense.
Is benzoic acid a stronger acid than HCl?
No, benzoic acid is not soluble in hydrochloric acid. However if you boil the benzoic acid to where it is water soluable and add hydrochloric acid it forms it back into the solid
What are the uses of ethyl benzoate?
Ethyl benzoate is a colorless to pale yellow colored chemical compound with a pleasant wintergreen mint flavor used as a food flavoring agent. It is alse called Benzoic acid, ethyl ester; Benzoic ether; Benzoyl ethyl ether; Ethyl benzenecarboxylate ; Ethyl benzoate (natural); Ethylester kyseliny benzoove; Ethylester kyseliny benzoove [Czech] and so on.Properties of Ethyl benzoateMelting point: -34 °CPolar Surface Area: 26.3 Å2Index of Refraction: 1.504Molar Refractivity: 42.65 cm3Molar Volume: 143.8 cm3Surface Tension: 35.8 dyne/cmDensity: 1.044 g/cm3Flash Point: 88.9 °CEnthalpy of Vaporization: 44.8 kJ/molBoiling Point: 211.7 °C at 760 mmHgVapour Pressure: 0.18 mmHg at 25°CUse of Ethyl benzoateBecause of its pleasant mixed fruity and woody odor, Ethyl benzoate is used as a perfume scent under the name essence de niobe.Ethyl benzoate is a volatile compound and tends to cause irritation of skin, eyes and respiratory tract, if inhaled. Moreover, it tends to react adversely with acidic and alkaline substances and also with oxidizing agents. Considering all these, this compound needs to be stored in airtight and non-corroding containers away from direct sunlight. It needs to be stored in a cool, dry and well ventilated place.
Why is vacuum filtration faster than gravity filtration?
Vacuum filtration is used instead of gravity filtration in order to achieve a dryer product in less time. The faster process of vacuum filtration allows the slurry to remain cold and in cases such as with benzoic acid more crytals will remain formed at colder temperatures. Gravity filtration is most useful when the solid is to be discarded and the filtrate (the liquid that flows through the filter paper) kept. Vacuum filtration is often faster than gravity filtration and is most useful if the solid must be kept or if a filtration must be done rapidly. A vacuum from an aspirator or a vacuum pump is used to pull the liquid through a funnel containing a piece of filter paper, while the solid is left on the paper.

Is Benzoic acid intensive or extensive?
