A para-methoxy protected benzaldehyde useful in preparation of treprostinil, and of formula: (Formula (1)) is prepared by subjecting to Claisen re-arrangement a substituted benzaldehyde of formula (1a): (Formula (Ia)) to form the m-hydroxy-substituted benzaldehyde of formula (1b): (Formula (Ib)) and then reacting compound (1b) with a p-methoxybenzyl (PMB) compound to form a PMB-substituted benzaldehyde of formula (1). 

Protected aldehydes for use as intermediates in chemical syntheses, and processes for their preparation

Disclosed is an ink carrier and a method for forming same, and a phase change ink including same. The ink carrier comprises a colloidal dispersion of at least one of silica nanoparticles and metal oxide nanoparticles. The ink carrier can also include a low melting wax, and a gelling agent. The ink carrier exhibits a substantially uniform distribution of the nanoparticles so that they are discretely distributed therewithin, and are substantially resistant to the aggregation of the nanoparticles distributed therewithin.
