Embodiment
All features disclosed in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and (or) step, all can combine by any way.
Arbitrary feature disclosed in this specification sheets (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Polyvinyl chloride (PVC) omnipotent internal lubricant, comprise higher alcohols, catalyzer, modification of colour agent and phthalic anhydride, described higher alcohols are made up of stearyl alcohol and hexadecanol, and described higher alcohols are 3.54-3.9: 1 with the charged material weight ratio of phthalic anhydride.
The proportioning calculation of parameter of above-mentioned higher alcohols and phthalic anhydride is as follows:
1, higher alcohols are made up of stearyl alcohol and hexadecanol, and its molecular-weight average is:
270 (C
18alcohol molecular weight) * 70%+242 (C
16alcohol molecular weight) * 30%=262
2, the calculating of stoichiometric
Calculate often to criticize 500kg higher alcohols gauge, the theoretical charging capacity of its phthalic anhydride is:
(148*500)/(2*262)＝141(kg)
The feed ratio of higher alcohols and phthalic anhydride is 3.54: 1 (weight)
3, the calculating of actual proportioning
Owing to considering the volatilization loss under hexadecanol and stearyl alcohol high temperature, the proportional quantity of general higher alcohols should suitably increase, and experimentally document is advisable with excessive 0.1-0.2mol.
(1), during the excessive 0.1mol of higher alcohols, throw 500kg higher alcohols, should throw phthalic anhydride amount is:
(148*500)/(2.1*262)＝134.5kg
Namely the ratio of components of higher alcohols and phthalic anhydride is 3.71: 1 (weight)
(2), during the excessive 0.2mol of higher alcohols, throw 500kg higher alcohols and should throw phthalic anhydride amount and be:
(148*500)/(2.2*262)＝128.3kg
Namely the ratio of components of higher alcohols and phthalic anhydride is 3.9: 1 (weight)
