(11) Performance Test:

(12) The performance of the products obtained in Embodiments 1-9 was tested. See Table 1 for the test results. Where:

(13) Burning test: The burning test was carried out according to the American ASTM-E681-01 standard, wherein the LFL is the lower limit value of the combustion limit, and a larger LFL value leads to lower combustibility.

(14) COP test: The products obtained in Embodiments 1-9 and HFO-1234yf were respectively mixed with lubricants and ether compounds, and then the performance of the mixtures was tested. The COP value of HFO-1234yf and the COP values of the products obtained in Embodiments 1-9 were determined at different evaporation temperatures and condensing temperatures.
