is there a reference for a relation to find the specific heat (Cp) for monoethanolamine as a function of temperature ? for example Cp= A+BT+CT^2+D^3 

 

thank you

Vapor or liquid pure component? Aqueous liquid solutions? Please be specific.

The source below has some tabulated data for data from 52°F to 86°F

Do you have access to Aspen Plus or HYSYS?  If so, you can do many things.  You can access DIPPR and retrieve the liquid Cp polynomial.  You can generate Cp's at the temperatures you are interested in, such as:

 

TEMP PRES LIQUID CP MONOE-01
C bar cal/gm-K
0 1.01325 0.547961
5 1.01325 0.55012
10 1.01325 0.552436
15 1.01325 0.5549
20 1.01325 0.557507
25 1.01325 0.560249
30 1.01325 0.56312
35 1.01325 0.566113
40 1.01325 0.569222
45 1.01325 0.572441
50 1.01325 0.575763
55 1.01325 0.579184
60 1.01325 0.582697
65 1.01325 0.586298
70 1.01325 0.589982
75 1.01325 0.593745
80 1.01325 0.597583
85 1.01325 0.601492
90 1.01325 0.605468

Hi ,

Check for the link above , page 50 you will find a relation  Cp =fct (temp) . Check for the domain of validity  T  (303-353 K) .  Linear relation Cp= aT+b 

Good luck

Hi,

Another reference: Yaw's handbook of thermodynamic and physical properties of chemical compounds 

 

CP liquid = A+BT+CT2+DT3  (joule/mole K)

C2H7NO

A 125.185

B 0.5798

C -1.5031 E-3

D 1.8061 E-6

 

temp domain ( 294-541 ) Kelvin

 

Good luck
