Paknikar, S.K.; Patel, J. (Proc. 11. Int. Congress on Essential Oils, Fragrances and Flavours. 1989; 105-.)
Newer methods of the synthesis of Cis-Jasmone, Part 1

Kirtany, J.K. (PAFAI Journal: Official organ of the Perfumes and Flavours Association of India. 11(4); 1989; 17-29.)
Catalytic redox reaction of nitric-oxide and carbon-monoxide on perovskites

Salker, A.V.; Chakrabarty, D.K.; Keer, H.V. (Indian Journal of Chemistry Section A-Inorganic Bio-Inorganic Physical Theoretical and Analytical Chemistry. 28(6); 1989; 458-462.)

Kinetics of oxidation-reduction reaction between CO and NO over perovskite catalysts LaMnO3 and LaCoO3, prepared by ceramic and wet methods, has been studied in the temperature range of 473-1000 K. Results have been discussed ...
Electron spin resonance of some vanadium oxides

Salker, A.V. (Indian Journal of Technology. 27(10); 1989; 501-502.)

Vanadium oxides, except V2O5 show phase transitions at critical temperatures (Tt). Above Tt they show metallic behaviour and are semiconductors below Tt. Electron spin resonance spectrum of these oxides were recorded at ...
Synthesis of 3 naturally-occurring diispropylmethylphenols

Ramanamma, C.V.; Dinge, A.S.; Paknikar, S.K. (Indian Journal of Chemistry Section B-Organic Chemistry Including Medicinal Chemistry. 28(6); 1989; 517-519.)
Thermal properties of magnesium bisulphite hydrazinate hydrate

Budkuley, J.S.; Patil, K.C. (Thermochimica Acta. 153(1); 1989; 419-422.)

As part of our research programme on hydrazine hydrate-sulphur dioxide-metal ion systems, metal sulphite hydrazinate hydrates [1] MSO3xN2H4.yH2O, have been synthesized, where M = Fe, Mn, Co, Ni and Zn. The thermal properties ...
Synthesis of coumarins by transfer of C sub(3 sup(-)) unit of cinnamic-acids to phenols using polyphosphoric acid

Bhattacharjee, J.; Paknikar, S.K. (Indian Journal of Chemistry Section B-Organic Chemistry Including Medicinal Chemistry. 28(3); 1989; 205-207.)

The reaction of cinnamic acid derivatives with different phenols in the presence of polyphosphoric acid gives coumarins in a single step, which involves transfer of the C sub(3 sup(-)) unit of cinnamic acids to the phenols ...
Synthesis and thermoanalytical properties of mixed metal sulfite hydrazinate hydrates .1.

Budkuley, J.S.; Patil, K.C. (Synthesis and Reactivity In Inorganic and Metal-Organic Chemistry. 19(9); 1989; 909-922.)

Mixed metal sulfite hydraxinate hydrates with iron MFe2(SO3)3.6N2H4.2H20 have heen synthesized, where M = Mg, Mn, Co, Ni and Zn. These complexes are characterized by chemical analyses and infrared spectra. The thermoanalytical ...
Applicability of four recent models to the discharge behaviour of different phases of MnO2 in alkaline and acidic/neutral electrolytes

Desai, B.D.; Dhume, R.A.S.; Kamat-Dalal, V.N. (Journal of Applied Electrochemistry. 18(1); 1988; 62-74.)

Manganese dioxides belonging to different crystalline phases were discharged in 9 M KOH and 5 M NH4Cl+2 M ZnCl2 at a constant current of 1 mA 0.1 g. These phases were characterized by X-ray diffractometry and chemical ...
Synthesis of (-)-Biflora-4,10(19), 15-Triene, a novel diterpene from the defensive secretion of cubitermes (termite) soldiers

Paknikar, S.K.; Greene, A.E. (Journal of Natural Products. 51(2); 1988; 326-327.)
