 Three years later, he published the hydrate dissociation curve in the range 267 K to 283 K (-6 to 10°C).Tamman & Krige measured the hydrate decomposition curve from 253 K down to 230 K in 1925 and Frost & Deaton (1946) determined the dissociation pressure between 273 and 283 K (0 and 10°C).Takenouchi & Kennedy (1965) measured the decomposition curve from 45 bars up to 2 kbar (4.5 to 200 MPa).
