Alkyd Calculations


ALKYD CALCULATIONS VERY USEFULL WHEN WE DESIGN AN ALKYD. I PERSONALLY USED THESE CALCULATIONS AND DESIGNED MANY ALKYDS SUCCESSFULLY. THESE ARE ALL AVAILABLE IN T.C. PATTON BOOK.
ON THE BASIS OF THESE CALCULATIONS I PREPARED AN EXCEL SPREADSHEET WITH FUNCTIONS, SO THAT WHEN WE ENTER FORMULATION INSTANTLY WE GET ALL CALCULATED RESULTS.  IF YOU ARE INTEREST, PLEASE SEND ME AN EMAIL FOR EXCEL SHEET OF ALKYD CALCULATIONS.



                                                                 INPUT
MOLECULAR WEIGHT =      ---------------------------------------------
                                                                   (   INPUT  X  ACID VALUE  )
                                           (mo--ea)  +      ( -----------------------------  )
                                                                   (                   56100          )

                                             ( ea --mo ) X 56100
ACID NUMBER GEL = ---------------------------------
                                                     INPUT

                                          2 ea
FUNCTIONALITY =      ---------------
                                           mo

                                                           ACID QUANTITY
WATER OF REACTION = --------------------------------------- X 18   (Calculate for each Acid RM and total it)
                                                     MOLECULAR WEIGHT

YIELD = INPUT -- WATER
                                                        mo
ALKYD CONSTANT = K =           -------------
                                                        ea

                                                       eb
EXCESS HYDROXY = R =        ---------------- X 100 -- 100
                                                       ea

                                  QUANTITY OF OIL X 100
OIL LENGTH = -------------------------------------------
                                                 YIELD

                                                    ( eb -- ea ) X 56100
HYDROXYL NUMBER = ---------------------------------------  +  ACID VALUE
                                                             YIELD

Hi AKUNDI!

I liked your excell file. Good job!

I have one ask:
Why do you calculate the Molecular wheight and Acid number gel using the Total? I use to the yeld.

My method is incorrect? What do you talk about?

Thanks.

hello sir, I had a doubt that i would like to discuss
Suppose if i want to make a water reducible polyester using trimelletic anhydride by functional acid groups to nuetralize and form salt which will allow water dilutability, and i want want the final acid value to be 60mg KOH/ g sample, how will you calculate the amout of TMA required??

I am going to carry out reaction in two steps.
1) Making polyester polyol with excess polyol and diacid
2) After polyol formation is complete, addition of TMA to achieve functional acid groups for nuetralization

THANKING YOU,
REGARDS.
