The invention discloses a sustainable chemical process of reduction of 4-methoxy-2-nitroaniline to 4-methoxy benzene-1,2-diamine, wherein the said process is carried out using a neutral reaction medium and comprises inherent recycling of said neutral reaction medium in a plurality of cycles, each of said cycles has ...

This invention relates to a process for the reduction in general and in particular to reduction of nitro (R-NO2) or nitroso (R-NO) compounds into corresponding amino compounds R-NH2 with either reduction or separation or both reduction and separation of amines in water and / or water immiscible solvent either high b...

The present invention relates to a sustainable chemical process of green reduction of R-NO2 or R-NO into corresponding R-NH2 that produces greener R-NH2 in good yields and selectivity with large number of recycle of mother liquor. The process creates sustainable and closed loop of water allowing inherent recycles of...

Isolation of Naphthalene Sulphonic Acid Compounds is achieved with acidification of alkali fusion mixture with dilute sulphuric acid to precipitation at the predetermined conditions temperature, time and pH and Naphthalene Sulphonic Acid Compounds is separated as a partial alkali metal salt by precipitation and sepa...
