ДВК конечный продукт реакции ацетона и формальдегида. По идее если долго настаивать то должно что то выйти. Научных статей я так и не смог найти по ДВК. Но синтез дибензальцетона имется. ДВК в теории что то похожее
Если настоять ацетон формальдегид и щелочь в тепле долгое время там должен быть ДВК. При дабавлении амина должен быть пиперидон. Вопрос конечно как его выделить.
Ниже используют уксусную кислоту как растворитель. Она выполняет роль катализатора. Точнее соли аммония идут как катализатор. Триацетонамин вобще без растворителей варят или в спирту. Сыпят ток хлорид аммония например

general,
0.2 mole of the amine or of ammonium acetate was dis-
solved in 20 cc. of glacial acetic acid, and 0.4 mole of alde-
hyde and 0.2 mole of ketone added to this solution. The
mixture was heated to the boiling point and then allowed
to cool to room temperature. When the product sepa-
rated as a crystalline solid on cooling, it was filtered,
washed and recrystallized. The free bases were converted
to the hydrochlorides either by the addition of concen-
trated hydrochloric acid or by passing hydrogen chloride
into an ether solution of the base. When an oil separated,
the base was converted directly to the hydrochloride and
purified by crystallization. The hydrochloride was con-
verted to the free base by adding aqueous ammonia to an
alcohol solution, and the base precipitated by dilution with
water.
Although the molar ratio of amine: aldehyde: ketone
usually was 1:2:1 as required by the equation, it fre-
quently was desirable to reduce the amount of the alde-
hyde since in some cases the unreacted aldehyde interfered
with the purification of the product. The per cent. yield
was calculated from the amount of aldehyde taken for the
reaction. The results are summarized in Table I. It
should be stated that the conditions for preparing and iso-
lating these compounds are not necessarily the optimum.
The object of the present investigation was merely to ob-
tain a sufficient quantity of the desired product
