Meaning of the verb from old scientific text "colirt"

Question

I am comparing machine translations of a paragraph from 1890s Beilstein Handbook for an educational paper. There is a word which I cannot find in a dictionary: The topic is on the occurrence of amygdalin (a sugar which causes bitterness in some almonds), where it occurs and how it is extracted.

Bittere Mandeln werden durch wiederholtes Pressen möglichst vom fetten Oele befreit und dann erst mit 2 Thln. und hier noch einmal mit 1 1⁄2 Thln. Alkohol ausgekocht. Die alkoholischen Auszüge filtrirt man, nach dem Erkalten, ab und destillirt den Alkohol ab. Den Retortenrückstand colirt man und lässt ihn 24 Stunden stehen, worauf man das ausgeschiedene Amygdalin mit kaltem Alkohol anrührt und dann auspresst. Das Auspressen, nach dem Anrühren mit neuen Mengen Alkohol, wird wiederholt und das Amygdalin endlich aus heißem Alkohol umkrystallisirt.

It seems colirt represents collected or cooled? If this is an old spelling, what is the modern spelling?

Both Google Translate and DeepL do not recognize it. This word is also absent from Beilstein Dictionary (an official dictionary of the handbook users).

Thanks. EDIT: For the sake of confirmation for the second poster (der bender), I searched Google Scholar for "colirt man" and the context is

[with spelling mistakes from scanned reading:

1) Methode in folgender Weise ab: Die zu untersuchenden Massen werden mit Wasser, das vorher mit Phosphorsgure schwach anges~tuert worden ist, bis zu einem dtlnnen Brei versetzt und 1-2 Stunden lang bei 60--800 digerirt; darauf colirt man dureh ein leinenes Tuch

2) Nierauf colirt man die Flussigkeit moglichst schnell durch ein leinenes Tuch...

It appears colirt is indeed koliert as suggested.

Answer 1

Among many other changes, the German Orthographic Conference of 1901 (a more detailed article is available in German Wikipedia) allowed to spell many words with K or Z which was written with C before, depending on their pronunciation. In most cases the version with C still stayed a valid version:

• C → Z

  central → zentral
  social → sozial
  civil → zivil
  Centimeter → Zentimeter
  Citrone → Zitrone

• C → K

  Compagnie → Kompanie
  Redacteur → Redakteur
  Conto → Konto
  Corpus → Korpus
  Cöln → Köln

• both changes in one word

  Accent → Akzent
  Circus → Zirkus
  Concept → Konzept
  Concert → Konzert

The versions with c was used less frequent in the next decades, and today in most of all cases the version with c is no longer valid.

I have no evidence for this specific word, but I am very sure, that in 1901 they also changed

coliren → kolieren

(the change of ending -iren to -ieren was another change from 1901)

Im PharmaWiki you find a description of this word. It says:

kolieren = durch ein Tuch filtern

Wissen.de says:

kolieren = durch ein Tuch seihen

Both explanations translate to

to filter through a cloth

I think that seihen is the better matching synonym. Both verbs (filtern, seihen) translate to to filter in english, but when you use filtern then the pores of the filter are so small, that you can't see them with naked eye. When you use seihen or kolieren then the pores of the filter are much bigger. They are so big, that you can see them with your naked eye.

Etymology

The word kolieren, coliren has its origin in the latin word

colare = to filter, to sieve

Answer 2

This is an alternate (archaic) way of writing

kolieren

which simply means "to filtrate", or "to strain"

Answer 3

I guess that this may relate to the word sammeln or english collect.

Reasons why i think tofros anwser is not applicable is the fact that a already filtered cooled and then destilled substance most likely does not require additional filtering.

Where as the product you get by filtration cooling and destillation of an alcoholic extract is likely to be of solid form and due to the nature of the substance of little quantity (and small scale). And all these particles have to be collected for further processing.
