According to the Histosearch link, Klotz solution - whatever that is - is used to preserve color in specimens.
I'd recommend looking up the Kayserling series of fixatives if that's what needed. The chloral hydrate is probably there as a preservative. It could probably replaced with ethanol, glycerol, phenol, or thymol. Chloral hydrate is now a controlled substance, because of its use as a sleeping potion (Mickey Finn) often with fatal consequences, since the fatal dose is only 3 or 4 times the clinical dose. Probably what killed Marilyn Monroe.
