Solubility and nucleation in l(+)-ascorbic acid–methanol–ethanol–water system

Some features of metastable zone width of various systems determined by polythermal method

“…3 shows the plots of lnc 0 against 1/T 0 for KTMC, 9 KTB 14 and LAA. 10 The solubility data reported in the literature in weight fraction were used to calculate DH s in these three cases. The values of DH s for PPP and POP are taken from ref.…”

“…In the present work, experimental data on the metastable zone width of the following six compounds were selected for the analysis using the recent approaches: keto-1,2,3,4-tetrahydro-6methylcarbazole (KTMC), 9 L(+)-ascorbic acid (LAA), 10 3-nitro-1,2,4-triazol-5-one (NTO), [11][12][13] potassium tetraborate tetrahydrate (KTB), 14 1,3-dipalmitoyl-2-oleoylglycerol (POP), 15 and tripalmitoylglycerol (PPP). 15 KTMC is a useful starting material for the synthesis of antibacterial and antifungal agents and antidepressant drug, 9 LAA is the popular vitamin C, NTO is an explosive, 11,13 KTB is used in lubrication oil, disinfectant and detergent industries, 14 while PPP and POP are popular fats contained in palm oil.…”

Effect of cooling rate on the critical undercooling for crystallization

“…(20) is so slightly curved that in a not too wide experimental q range it can easily be mistaken for a straight line. This explains the fact that, experimentally, ln u c is often reported as being linear with ln q (e.g., [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]) and, thereby, in agreement with Nyvlt's equation [1]. The question therefore arises: is it possible to approximate u c (q) from Eq.…”

“…In the years that followed, this equation was found to be successful in describing many experimental DT c (q) data on cooling crystallization [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Its use, however, has not contributed to a deeper understanding of crystal nucleation and growth mechanisms, because it contains two semi-empirical parameters to which, in Nyvlt's own words, ''a concrete physical meaning should not be ascribed'' [1].…”

Size-dependent nucleation and growth kinetics model for potassium chloride—Application in Qarhan salt lake

“…A number of researchers have studied the crystal growth process of KCl and several crystal growth mechanisms were proposed in the literature [7][8][9]. However, there are some problems in industrial KCl production in Qarhan salt lake.…”
