The reaction between hexamethylenediisocyanate and 1-pentanol in toluene was studied by means of reversed-phase liquid chromatography. By employing this method, it was possible to determine all components of the reaction mixture including both products, i.e. N-(6-isocyanate hexyl)pentylcarbamate and N,N'-bis(pentyloxycarbonyl)hexamethylenediamine. Relations for the calculation of kinetic constants were derived assuming a competitive consecutive second-order reaction. It was demonstrated that the reaction involved in this case is indeed a second-order reaction, and the rate constants of the first and second consecutive reactions were determined.

ABSTRAKTujuan dari penelitian ini untuk mengkaji kinetika fotodegradasi methylene blue (MB) menggunakan komposit Ag3PO4/Ag/HAp tulang ikan kakap merah (Lutjanus sp.).  Serbuk tulang ikan yang dikalsinasi hingga 1000ºC dan direaksikan dengan AgNO3 dengan rasio mol 5:1 (Ag:HAp) dan dihasilkan komposit Ag3PO4/Ag/HAp. Larutan MB diinteraksikan dengan komposit dengan variasi waktu 5-180 menit dibawah radiasi cahaya tampak. Konsentrasi MB yang tersisa ditentukan ditentukan dengan spektrofotometer UV-Vis dan data yang diperoleh dianalisis dengan model kinetika reaksi orde ke-1 dan ke-2. Hasil penelitian menunjukkan bahwa fotodegradasi MB oleh komposit Ag3PO4/Ag/HAp mengikuti model kinetika fotodegradasi orde ke-2. ABSTRACT The purpose of this research was to study the kinetics of methylene blue (MB) photodegradation using composite Ag3PO4/Ag/HAp bone fish of red snapper (Lutjanus sp.). Fish bone powder which was calcined to 1000ºC and reacted with AgNO3 with mole ratio of 5 : 1 (Ag: HAp) and produced Ag3PO4/Ag/HAp composite. MB solution was interacted with composites with variation of time 5-180 minutes under visible light radiation. The remaining MB concentrations determined were determined by a UV-Vis spectrophotometer and the data obtained were analyzed with first and second order reaction kinetics model. The results showed that MB photodegradation by Ag3PO4/Ag/HAp composites followed the 2nd order photodegradation kinetics model.

Thermodynamics and kinetics of the reaction between thyroxine and antithyroxine antiserum has been studied using the concentration and temperature conditions usual in the radioimmunoanalysis. The reaction is assumed to be homogeneous and of the second order. Because of the initial concentrations of thyroxine and of the free bonds of the heterogeneous population of antibodies present in the used antiserum the rate constant equation for second-order reaction has been used in the integrated form. The relative rate constants have been obtained and the activation energy of the reaction in absence of the serum proteins in the reaction mixture or, respectively, in the presence of the euthyroidic serum has been calculated. The nature of the effect of so-called deblockators (J) (8-anilino-1-naphthalene sulphonic acid and tiomersal) on the reaction rate and on the change of the reaction enthalpy (or entropy) has also been investigated. The association constant of this reaction has been evaluated from the radioimmunoanalytical data transformed by the Scatchard relation, modified for the conditions of thyroxine radioimmunoanalysis.
