Rasayani is located on SH-83, about five kilometeres off NH4. Rasayani is composed of a cluster of villages namely Ambivali, Dapivali, Mohopada, Chambarli, Vaveghar, Rees, Karade, Gulsunde, Turade, Savle. Apparently, the name Rasayani was originally coined by the noted Marathi writer P.L. Deshpande. There are many chemical manufacturing and processing companies located here. The word "Rasayan - रसायन" in devnagri script means Chemical and India's firest Chemicals industry "Hindustan Organic Chemicals Ltd." was established here in 1960's, hence he decided to name the place "Rasayani". It derives its name mainly from chemical industry HOCL. As of today the biggest player remaining is Reliance, which has a petrochemicals and fibre plant in the area.
