Abstract
Separating
water‐in‐heavy
oil
(W/HO)
emulsions
at
low
(room)
temperature
is
challenging
when
exploiting
heavy
oil.
We
propose
an
adaptable
strategy
for
constructing
Si/O‐doped
demulsifiers.
A
nonionic
demulsifier
(APBMP)
has
been
synthesized
based
on
polysiloxane
modified
by
allyl
polyether
and
butyl
acrylate.
APBMP
achieves
95.97%
dehydration
within
5
min
W/HO
288.15
K
complete
in
15
323.15
K.
Mechanistic
studies
found
that
doping
Si/O
into
the
molecules
increases
number
of
hydrogen
bond
sites,
which
enables
demulsifiers
to
quickly
disperse
natural
stabilizers
(e.g.,
asphaltenes)
replace
them
oil–water
interfacial
film.
The
prefer
occupy
sites
rather
than
dissolve
bulk
or
water
phases.
Driven
hydrogen‐bond‐dominated
noncovalent
interactions,
film
softened,
reconstructed,
broken.
These
findings
provide
insights
developing
novel
materials
separations
a
low‐carbon
way.
