Acetal
The two R' groups can be equivalent to each other (a "symmetric acetal") or not (a "mixed acetal"). Although many compounds contain an acetal functional group, at least two acetal compounds are called "acetal" for short: Polyoxymethylene (POM) plastic wikipedia.org

Acetal Plastic Material Properties: High Strength, Low Friction ...
Acetal Properties and Material Options. Homopolymer vs. Copolymer - Acetal is available in both homopolymer (Delrin® 150) and copolymer. Homopolymer acetal (Delrin®) has superior room temperature strength, stiffness, and toughness. Copolymer acetal has excellent performance in continuous high heat and hot water environments.

3,9-Diethylidene-2,4,8,10-tetraoxaspiro(5.5)undecane
3,9-Diethylidene-2,4,8,10-tetraoxaspiro[5.5]undecane (DETOSU) is a bicyclic ketene acetal derived from the isomeric allyl acetal 3,9-divinyl-2,4,8,10-tetraoxaspiro bifunctional monomer, DETOSU is an important building block for polyorthoesters formed by the addition of diols to the activated double bond of the diketene acetal wikipedia.org

Carbohydrate acetalisation
The latter reagent in itself is an acetal and therefore the reaction is actually a cross-acetalisation. In aqueous solution ribose is 75% pyranose and 25% furanose and a different acetal 4 is formed. wikipedia.org

缩醛
缩醛（Acetal）是一类同一碳上连有两个烷氧基和一个氢的有机化合物。缩醛可由半缩醛继续与醇反应得到，而半缩醛可以由醛和醇反应得到。 缩醛在酸性水溶液中是不稳定的，但对碱和氧化剂是稳定的，因此可以用作羰基的保护基。 wikipedia.org
